Technical Field

[0001] This invention relates to an electronic component. Prior Technology

[0002] Japanese Patent Application Publication No. 2002-57543 discloses an electronic component in which a plurality of inductors and capacitors are formed in a multilayer body composed of stacked insulating layers, forming a plurality of LC resonators electromagnetically coupled by the inductors and capacitors. The inductors are formed by through-holes connected in the stacking direction of the insulating layers, and a coupling adjustment conductor formed by through-holes connected in the stacking direction of the insulating layers is disposed between at least two adjacent LC resonators in the plurality of LC resonators, and the coupling adjustment conductor is grounded. Summary of the Invention

[0003] One objective of this invention is to provide an electronic component that achieves miniaturization while simultaneously increasing its Q value.

[0004] (1) An electronic component of one embodiment of the present invention comprises: a blank formed by stacking a plurality of insulating layers, and a resonator disposed within the blank. The resonator has two conductors extending in the stacking direction of the plurality of insulating layers, and a connecting conductor connecting the two conductors. In at least one of the two conductors, when the conductor is viewed from the stacking direction, a first length in a direction orthogonal to the opposing direction of the two conductors is longer than a second length in the opposing direction. In a graph where the horizontal axis is the value of the second length of the conductor and the vertical axis is the Q value, when the first value of the horizontal axis is set to X1, the second value of the horizontal axis is set to X2, the first Q value of the vertical axis at the first value X1 is set to Y1, and the second Q value of the vertical axis at the second value X2 is set to Y2, the slope of the graph (Y2-Y1) / (X2-X1) is negative.

[0005] In one embodiment of the electronic component of the present invention, when viewed from the stacking direction, the first length of at least one of the two conductors in a direction orthogonal to the opposing directions of the two conductors is longer than the second length in the opposing direction. This allows for an increase in the opening formed by the two conductors and the connecting conductor while avoiding an increase in the size of the blank in the opposing direction. Therefore, in this electronic component, miniaturization can be achieved while increasing inductance. In this configuration, in the electronic component, in a graph where the horizontal axis represents the value of the second length of the conductor and the vertical axis represents the Q (Quality Factor) value, when the first Q value at the vertical axis at the first value X1 is set to Y1, and the second Q value at the vertical axis at the second value X2 is set to Y2, the slope of the graph (Y2-Y1) / (X2-X1) is negative. This characteristic enables an increase in the Q value in the electronic component.

[0006] (2) In the electronic component described in (1) above, the second length of the conductor can also be 125 μm or less. In this configuration, the opening formed by the two conductors and the connecting conductor can be increased. Therefore, in the electronic component, inductance can be increased while achieving miniaturization.

[0007] (3) In the electronic component described in (1) or (2) above, a plurality of recesses may be provided on the side of the conductor, the plurality of recesses being arranged opposite each other in the opposite direction and extending in the lamination direction. In this configuration, the bonding strength between the blank and the conductor can be improved.

[0008] (4) In any of the electronic components described in (1) to (3) above, the first length of each of the two conductors may be longer than the second length, and the first and second lengths of the two conductors may be the same. In this configuration, the cross-sectional area of ​​the two conductors can be increased, and therefore, the resistance of the two conductors can be reduced. Therefore, in electronic components, the Q value can be improved.

[0009] (5) In any of the electronic components described in (1) to (4) above, the direction orthogonal to the opposing directions of the two conductors when viewed from the stacking direction is along the length of the blank. In this configuration, a resonator can be efficiently arranged within the blank of the conductor.

[0010] (6) Among the electronic components in any of (1) to (5) above, the resonator may also have a complex array of two conductors and a group of connecting conductors.

[0011] (7) An electronic component of one embodiment of the present invention comprises: a blank formed by stacking a plurality of insulating layers, and a resonator disposed within the blank. The resonator has two conductors extending in the stacking direction of the plurality of insulating layers, and a connecting conductor connecting the two conductors. In at least one of the two conductors, when viewed from the stacking direction, the first length in the direction orthogonal to the opposing direction of the two conductors is longer than the second length in the opposing direction. In a graph where the horizontal axis is the width dimension in the opposing direction of the two conductors and the vertical axis is the Q value, when the first value of the horizontal axis is set to X1, the second value of the horizontal axis is set to X2, the first Q value of the vertical axis at the first value X1 is set to Y1, and the second Q value of the vertical axis at the second value X2 is set to Y2, the value of (Y2-Y1) / (X2-X1) is negative.

[0012] In one embodiment of the electronic component of the present invention, when viewed from the stacking direction, the first length of the direction orthogonal to the opposing directions of the two conductors in at least one of the two conductors is longer than the second length of the opposing direction. Therefore, in the electronic component, the opening formed by the two conductors and the connecting conductor can be increased while avoiding an increase in the size of the blank in the opposing direction. Thus, in the electronic component, inductance can be increased while achieving miniaturization. In this configuration, in the electronic component, in a graph where the horizontal axis represents the width dimension in the opposing direction of the two conductors and the vertical axis represents the Q (Quality Factor) value, when the first Q value at the vertical axis at the first value X1 is set to Y1, and the second Q value at the vertical axis at the second value X2 is set to Y2, (Y2-Y1) / (X2-X1) is negative. By possessing this characteristic, the Q value can be improved in the electronic component.

[0013] According to one embodiment of the present invention, it is possible to improve the Q value while achieving miniaturization. Simple Explanation of the Diagram

[0015] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Furthermore, in the description of the drawings, the same or equivalent elements are labeled with the same symbols, and repeated descriptions are omitted.

[0016] [First Embodiment] FIG1 is a perspective view of the electronic component according to the first embodiment. As shown in FIG1, the electronic component 1 includes a blank 2 and a resonator 3. In FIG1, the blank 2 is represented by a two-point chain line.

[0017] The blank 2 is in the shape of a cuboid. The cuboid shape includes: a cuboid with chamfered corners and edges, and a cuboid with rounded corners and edges. The blank 2 has a pair of end faces 2a and 2b, a pair of main faces 2c and 2d, and a pair of side faces 2e and 2f, which are one of its outer surfaces. End faces 2a and 2b face each other. Main faces 2c and 2d face each other. Side faces 2e and 2f face each other. Hereinafter, the facing direction of end faces 2a and 2b is designated as the first direction D1, the facing direction of main faces 2c and 2d is designated as the second direction D2, and the facing direction of side faces 2e and 2f is designated as the third direction D3. The first direction D1, the second direction D2, and the third direction D3 are approximately orthogonal to each other.

[0018] End faces 2a and 2b extend in the second direction D2, connecting to main faces 2c and 2d. End faces 2a and 2b also extend in the third direction D3, connecting to side faces 2e and 2f. Main faces 2c and 2d extend in the first direction D1, connecting to end faces 2a and 2b. Main faces 2c and 2d also extend in the third direction D3, connecting to side faces 2e and 2f. Side faces 2e and 2f extend in the first direction D1, connecting to end faces 2a and 2b. Side faces 2e and 2f also extend in the second direction D2, connecting to main faces 2c and 2d.

[0019] Main surface 2d is the mounting surface, for example, when electronic component 1 is mounted on other electronic devices (e.g., circuit substrates or multilayer electronic components), it is the surface facing other electronic devices. End surfaces 2a and 2b are surfaces that are continuous from the mounting surface (i.e., main surface 2d).

[0020] The length of the billet 2 in the first direction D1 is longer than the length of the billet 2 in the second direction D2 and the length of the billet 2 in the third direction D3. The first direction D1 is the length direction of the billet 2. The length of the billet 2 in the second direction D2 is shorter than the length of the billet 2 in the third direction D3. That is, in this embodiment, the end faces 2a and 2b, the main faces 2c and 2d, and the side faces 2e and 2f are rectangular. The length of the billet 2 in the second direction D2 can be the same as the length of the billet 2 in the third direction D3, or it can be longer than the length of the billet 2 in the third direction D3.

[0021] Furthermore, in this embodiment, the term "equal" can mean not only equal, but also values ​​that include minor differences or manufacturing errors within a predetermined range. For example, if a plurality of values ​​are within the range of ±5% of the average of the plurality of values, then the plurality of values ​​are defined as equal.

[0022] The billet 2 is formed by stacking a plurality of billet layers (insulator layers) 6 on the second direction D2. That is, the stacking direction of the billet 2 is the second direction D2. In the actual billet 2, the plurality of billet layers 6 can be integrated either to the extent that the boundaries between the layers are not visible, or in a way that the boundaries between the layers are visible.

[0023] The blank layer is, for example, composed of a sintered body of ceramic blank containing a dielectric material. The dielectric material includes, for example, at least one selected from BaTiO3-based materials, Ba(Ti,Zr)O3-based materials, (Ba,Ca)TiO3-based materials, glass materials, or alumina materials.

The second conductor 14 is positioned near the side 2f of the blank 2. The second conductor 14 is positioned opposite the first conductor 13 in the third direction D3. The first conductor 13 and the second conductor 14 are separately positioned in the third direction D3. The second conductor 14 has a first end 14A and a second end 14B. The first end 14A of the second conductor 14 is connected to the inductor conductor 15. The second end 14B of the second conductor 14 is connected to the ground conductor 12.

[0030] Figure 3 is a cross-sectional view of the conductors (first conductor 13, second conductor 14). The cross-sections of the first conductor 13 and the second conductor 14 shown in Figure 3 are cross-sections along the planes of the first direction D1 and the third direction D3. As shown in Figure 3, the first conductor 13 and the second conductor 14 have the same shape and the same dimensions. When viewed from the second direction D2, the first length L1 of the first conductor 13 and the second conductor 14 in the first direction D1 is longer than the second length L2 in the third direction D3 (L1>L2). In this embodiment, the first length L1 and the second length L2 of the first conductor 13 and the second conductor 14 are each the same. In this embodiment, the second length L2 is, for example, 125 μm or less, preferably 100 μm or less. The second length L2 may, for example, be 20 μm or more.

[0031] The first conductor 13 and the second conductor 14 are arranged with a first length L1 along a first direction D1 and a second length L2 along a third direction D3. That is, the extension directions of the first conductor 13 and the second conductor 14 are orthogonal to the direction in which the first conductor 13 and the second conductor 14 are arranged (the third direction D3). Orthogonality includes approximately orthogonality, for example, it can include a range of about ±3°.

[0032] In this embodiment, the first conductor 13 and the second conductor 14 are in the shape of a plurality of overlapping circles (eight in the example shown in FIG3). Specifically, the first conductor 13 and the second conductor 14 are in the shape of a partial overlap of one pair of adjacent circles. For example, two adjacent circles overlap in such a way that the outer circumference of one circle passes through the center of the other circle. The side surfaces 13S and 14S of the first conductor 13 and the second conductor 14 are formed by curved surfaces. A plurality of recesses 13C and 14C are provided on the side surfaces 13S and 14S of the first conductor 13 and the second conductor 14. The recesses 13C and 14C extend in the second direction D2. The recesses 13C and 14C are arranged at predetermined intervals in the first direction D1. The recesses 13C and 14C are arranged in opposite positions in the third direction D3.

[0033] Figure 4 illustrates the resonator 3. As shown in Figure 4, the first conductor 13 and the second conductor 14 are arranged with a width (width dimension) W in the third direction D3. The width W is, for example, 600 μm. The width W is the distance between the end of the side 2e of the first conductor 13 and the end of the side 2f of the second conductor 14. That is, the width W is the maximum distance between the first conductor 13 and the second conductor 14 in the third direction D3.

[0034] Inductor conductor 15 constitutes an inductor. In this embodiment, as shown in Figures 1 and 2, inductor conductor 15 is rectangular. Inductor conductor 15 extends in a straight line along a third direction D3. Inductor conductor 15 is erected across the first end 13A of the first conductor 13 and the first end 14A of the second conductor 14. Inductor conductor 15 electrically connects the first conductor 13 and the second conductor 14.

[0035] Inductor conductor 16 constitutes an inductor. In this embodiment, inductor conductor 16 is rectangular. That is, inductor conductor 16 has the same shape as inductor conductor 15. Inductor conductor 16 extends in a straight line along a third direction D3. Inductor conductor 16 is electrically connected to inductor conductor 15 via connecting conductor 22 and connecting conductor 23. Inductor conductor 16 is arranged opposite to inductor conductor 15 in the second direction D2. Inductor conductor 16 electrically connects first conductor 13 and second conductor 14.

[0036] The capacitor conductor 17 is rectangular when viewed from the second direction D2. The capacitor conductor 17, together with the ground conductor 12, constitutes a capacitor. The capacitor conductor 17 is connected to the second end 13B of the first conductor 13. The capacitor conductor 17 is positioned at a predetermined interval from the ground conductor 12 in the second direction D2.

[0037] Capacitor conductor 18 is electrically connected to second terminal conductor 11. Capacitor conductor 18 and second terminal conductor 11 are electrically connected via connecting conductors 24, 25, 26, 27, and 28. Capacitor conductor 18 is positioned at a predetermined interval from capacitor conductor 17 in the second direction D2.

[0038] Figure 5 is a graph showing the relationship between the second length L2 of the first conductor 13 and the second conductor 14 and the Q value. In Figure 5, the horizontal axis represents the second length L2 [μm] of the first conductor 13 and the second conductor 14, and the vertical axis represents the Q value. Figure 5 shows the results at a frequency of 9 GHz.

[0039] As shown in Figure 5, in electronic component 1, when the first value of the horizontal axis is set to X1, the second value of the horizontal axis is set to X2, the first Q value of the vertical axis at the first value X1 is set to Y1, and the second Q value of the vertical axis at the second value X2 is set to Y2, the slope of the curve is... (Y2-Y1) / (X2-X1) The slope is negative. That is, in electronic component 1, the first conductor 13 and the second conductor 14 are constructed in such a way that the slope of the curve under the above relationship is negative.

[0040] In the example shown in Figure 5, in electronic component 1, for example, X1 can be 20 μm, X2 can be 35 μm, Y1 can be 160.4, and Y2 can be 159.7. In this case, the slope of the curve is negative. In electronic component 1, for example, X1 can be 35 μm, X2 can be 50 μm, Y1 can be 159.7, and Y2 can be 158.6. In electronic component 1, for example, X1 can be 50 μm, X2 can be 65 μm, Y1 can be 158.6, and Y2 can be 156.9. In electronic component 1, for example, X1 can be 65 μm, X2 can be 95 μm, Y1 can be 156.9, and Y2 can be 149.0. In this embodiment, the Q value is maximum when the second length L2 is 20 μm.

[0041] As described above, in the electronic component 1 of this embodiment, when viewed from the second direction D2, the first length L1 of the first conductor 13 and the second conductor 14 in the first direction D1 is longer than the second length L2 of the third direction D3 (L1>L2). Therefore, in the electronic component 1, the opening formed by the first conductor 13, the second conductor 14, and the inductor conductor 15 can be increased while avoiding an increase in the size of the blank 2 in the third direction D3. Thus, in the electronic component 1, inductance can be increased while achieving miniaturization. In this configuration, in the electronic component 1, in a graph where the horizontal axis represents the value of the second length L2 of the first conductor 13 and the second conductor 14, and the vertical axis represents the Q (Quality Factor) value, when the first Q value at the first value X1 is set to Y1, and the second Q value at the second value X2 is set to Y2, the slope of the graph (Y2-Y1) / (X2-X1) is negative. In electronic component 1, by having this characteristic, the Q value can be improved.

The second inductor conductor 48 electrically connects the third conductor 45 and the fourth conductor 46.

[0056] Connecting conductor 49 forms an inductor. Connecting conductor 49 is connected to the second end 44B of the second conductor 44 and the second end 45B of the third conductor 45. Connecting conductor 49 electrically connects the second conductor 44 and the third conductor 45.

[0057] The capacitor conductor 50 is rectangular when viewed from the second direction D2. The capacitor conductor 50, together with the first ground conductor 41, constitutes a capacitor. The capacitor conductor 50 is connected to the second end 43B of the first conductor 43. The capacitor conductor 50 is positioned at a predetermined interval from the first ground conductor 41 in the second direction D2.

[0058] When viewed from the second direction D2, the capacitor conductor 51 is L-shaped. The capacitor conductor 51 is electrically connected to the terminal electrode 36. The capacitor conductor 51 and the terminal electrode 36 are electrically connected by a connecting conductor 52. The capacitor conductor 51 is positioned at a predetermined interval from the capacitor conductor 50 in the second direction D2.

[0059] In the resonator 70, an inductor is formed by a first conductor 43, a second conductor 44 and a first inductor conductor 47, and an inductor is formed by a third conductor 45, a fourth conductor 46 and a second inductor conductor 48. The resonator 70 has two groups (conductors and inductor conductors) that constitute an inductor.

[0060] Figure 8 is a graph showing the relationship between the second length L2 of the first conductor 43, the second conductor 44, the third conductor 45, and the fourth conductor 46 and the Q value. In Figure 8, the horizontal axis represents the second length L2 [μm] of the first conductor 43, the second conductor 44, the third conductor 45, and the fourth conductor 46, and the vertical axis represents the Q value. Figure 8 shows the results at a frequency of 3.5 GHz.

[0061] As shown in Figure 8, in electronic component 1A, when the first value of the horizontal axis is set to X1, the second value of the horizontal axis is set to X2, the first Q value of the vertical axis at the first value X1 is set to Y1, and the second Q value of the vertical axis at the second value X2 is set to Y2, the slope of the curve is... (Y2-Y1) / (X2-X1) The slope is negative. That is, in electronic component 1A, the first conductor 43, the second conductor 44, the third conductor 45 and the fourth conductor 46 are constructed in such a way that the slope of the curve under the above relationship is negative.

[0062] In the example shown in Figure 8, in electronic component 1A, for example, X1 can be 35 μm, X2 can be 65 μm, Y1 can be 132.3, and Y2 can be 128.3. In this case, the slope of the curve is negative. In electronic component 1A, for example, X1 can be 65 μm, X2 can be 95 μm, Y1 can be 128.3, and Y2 can be 126.1. In electronic component 1A, for example, X1 can be 95 μm, X2 can be 155 μm, Y1 can be 126.1, and Y2 can be 118.2. In this embodiment, the Q value is maximum when the second length L2 is 35 μm.

[0063] As described above, in the electronic component 1A of this embodiment, when viewed from the second direction D2, the first length L1 of the first conductor 43, the second conductor 44, the third conductor 45, and the fourth conductor 46 in the first direction D1 is longer than the second length L2 of the third direction D3 (L1>L2). Therefore, in the electronic component 1A, while avoiding an increase in the size of the blank 2 in the third direction D3, it is possible to increase the size of the openings formed by the first conductor 43, the second conductor 44, and the first inductor conductor 47, as well as the openings formed by the third conductor 45, the fourth conductor 46, and the second inductor conductor 48. Thus, in the electronic component 1A, miniaturization can be achieved while increasing the inductance. In this configuration, in electronic component 1A, in a graph where the horizontal axis represents the second length L2 of the first conductor 43, the second conductor 44, the third conductor 45, and the fourth conductor 46, and the vertical axis represents the Q (Quality Factor) value, when the first Q value at the vertical axis at the first value X1 is set to Y1, and the second Q value at the vertical axis at the second value X2 is set to Y2, the slope of the graph (Y2-Y1) / (X2-X1) is negative. By possessing this characteristic, electronic component 1A can achieve an increase in the Q value.

The cross-sections of the first conductor 72 and the second conductor 73 shown in Figure 10 are cross-sections along the planes of the first direction D1 and the third direction D3.

In this embodiment, the second length L2 is, for example, 125 μm or less, preferably 95 μm or less. The second length L2 may, for example, be 35 μm or more.

[0071] The first conductor 72 and the second conductor 73 are configured such that a first length L1 is along a first direction D1 and a second length L2 is along a third direction D3. That is, the extending directions of the first conductor 72 and the second conductor 73 are orthogonal to the direction in which the first conductor 72 and the second conductor 73 are arranged (the third direction D3). Orthogonality includes approximately orthogonality, for example, it may include a range of about ±3°.

[0072] In this embodiment, the first conductor 72 and the second conductor 73 are in the shape of a plurality of overlapping circles. Specifically, the first conductor 72 and the second conductor 73 are in the shape of a partial overlap of each of an adjacent pair of circles. For example, two adjacent circles overlap such that the outer circumference of one circle passes through the center of the other circle. The side surfaces 72S and 73S of the first conductor 72 and the second conductor 73 are formed by curved surfaces. A plurality of recesses 72C and 73C are provided on the side surfaces 72S and 73S of the first conductor 72 and the second conductor 73. The recesses 72C and 73C extend in the second direction D2. The recesses 72C and 73C are arranged at predetermined intervals in the first direction D1. The recesses 72C and 73C are arranged in opposite positions in the third direction D3.

[0073] Inductor conductor 74 constitutes an inductor. In this embodiment, as shown in FIG9, inductor conductor 74 is rectangular. Inductor conductor 74 extends along a third direction D3. Inductor conductor 74 is erected across a first end 72A of the first conductor 72 and a first end 73A of the second conductor 73. Inductor conductor 74 electrically connects the first conductor 72 and the second conductor 73.

[0074] Inductor conductor 75 constitutes an inductor. In this embodiment, inductor conductor 75 is rectangular. That is, inductor conductor 75 has the same shape as inductor conductor 74.

[0075] The capacitor conductor 76 is rectangular when viewed from the second direction D2. The capacitor conductor 76, together with the ground conductor 71, constitutes a capacitor. The capacitor conductor 76 is connected to the second end 73B of the second conductor 73.

[0077] Figure 11 is a graph showing the relationship between the second length L2 of the first conductor 72 and the second conductor 73 and the Q value. In Figure 11, the horizontal axis represents the second length L2 [μm] of the first conductor 72 and the second conductor 73, and the vertical axis represents the Q value. Figure 11 shows the results at a frequency of 13 GHz.

[0078] As shown in Figure 11, in electronic component 1B, when the first value of the horizontal axis is set to X1, the second value of the horizontal axis is set to X2, the first Q value of the vertical axis at the first value X1 is set to Y1, and the second Q value of the vertical axis at the second value X2 is set to Y2, the slope of the curve is... (Y2-Y1) / (X2-X1) The slope is negative. That is, in electronic component 1B, the first conductor 72 and the second conductor 73 are constructed in such a way that the slope of the curve under the above relationship is negative.

[0079] In the example shown in Figure 11, in electronic component 1B, for example, X1 can be 35 μm, X2 can be 65 μm, Y1 can be 125.6, and Y2 can be 123.8. In this case, the slope of the curve is negative. In electronic component 1B, for example, X1 can be 65 μm, X2 can be 95 μm, Y1 can be 123.8, and Y2 can be 118.7. In this embodiment, the Q value is maximum when the second length L2 is 35 μm.

[0080] As described above, in the electronic component 1B of this embodiment, when viewed from the second direction D2, the first length L1 of the first conductor 72 and the second conductor 73 in the first direction D1 is longer than the second length L2 of the third direction D3 (L1>L2). Therefore, in the electronic component 1B, the opening formed by the first conductor 72, the second conductor 73, and the inductor conductor 74 can be increased while avoiding an increase in the size of the blank 2 in the third direction D3. Thus, in the electronic component 1B, inductance can be increased while achieving miniaturization. In this configuration, in the electronic component 1B, in a graph where the horizontal axis represents the value of the second length L2 of the first conductor 72 and the second conductor 73, and the vertical axis represents the Q (Quality Factor) value, when the first Q value at the first value X1 is set to Y1, and the second Q value at the second value X2 is set to Y2, the slope of the graph (Y2-Y1) / (X2-X1) is negative. In electronic component 1B, this characteristic enables an increase in the Q value.

[0081] The embodiments of the present invention have been described above, but the present invention is not necessarily limited to the above embodiments, and various modifications can be made without departing from its spirit.

[0082] In the first embodiment described above, an example was given in which, when viewed from the second direction D2, the first length L1 of the first conductor 13 and the second conductor 14 in the first direction D1 is longer than the second length L2 of the third direction D3 (L1>L2). However, it is sufficient that, when viewed from the second direction D2, the first length L1 of at least one of the first conductor 13 and the second conductor 14 in the first direction D1 is longer than the second length L2 of the third direction D3. The same applies to the first conductor 43, the second conductor 44, the third conductor 45, and the fourth conductor 46 in the second embodiment, and the first conductor 72 and the second conductor 73 in the third embodiment.

[0083] In the first embodiment described above, the first conductor 13 and the second conductor 14 are described as having a plurality of overlapping circles and recesses 13C and 14C. However, the shapes of the first conductor 13 and the second conductor 14 are not limited to this. For example, the first conductor 13 and the second conductor 14 may also be rectangular, elliptical, etc. The same applies to the second and third embodiments.

[0084] In the above embodiments, the configuration of the terminal electrode (terminal conductor) is not limited.

[0085] In another embodiment of the present invention, the electronic component comprises: a blank formed by stacking a plurality of insulating layers, and a resonator disposed within the blank. The resonator has two conductors extending in the stacking direction of the plurality of insulating layers, and a connecting conductor connecting the two conductors. In at least one of the two conductors, when viewed from the stacking direction, a first length in a direction orthogonal to the opposing directions of the two conductors is longer than a second length in the opposing direction. In a graph where the horizontal axis represents the width dimension in the opposing direction of the two conductors and the vertical axis represents the Q value, when the first value of the horizontal axis is set to X1, the second value of the horizontal axis is set to X2, the first Q value of the vertical axis at the first value X1 is set to Y1, and the second Q value of the vertical axis at the second value X2 is set to Y2, the value of (Y2-Y1) / (X2-X1) is negative.

[0086] In the aforementioned electronic component, when viewed from the stacking direction, the first length of the direction orthogonal to the opposing directions of the two conductors in at least one of the two conductors is longer than the second length in the opposing direction. This allows for an increase in the opening formed by the two conductors and the connecting conductor while avoiding an increase in the size of the blank in the opposing direction. Therefore, in this electronic component, miniaturization can be achieved while increasing inductance. In this configuration, in the electronic component, in a graph where the horizontal axis represents the width dimension in the opposing direction of the two conductors and the vertical axis represents the Q (Quality Factor) value, when the first Q value at the vertical axis at the first value X1 is set to Y1, and the second Q value at the vertical axis at the second value X2 is set to Y2, the slope of the graph (Y2-Y1) / (X2-X1) is negative. This characteristic enables an increase in the Q value in the electronic component.
