BEST MODE FOR CARRYING OUT THE INVENTION
[0007] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. The drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the ratio of the sizes between parts, etc. are not necessarily the same as those in reality. Even when representing the same part, the dimensions and ratios may be represented differently in the drawings. In the present specification and each figure, the same reference numerals are given to the same elements as those described above with respect to the already shown figures, and the detailed description is omitted as appropriate.
[0008] (First Embodiment) FIG. 1 is a schematic plan view illustrating the sensor according to the first embodiment. FIG. 2 is a schematic cross-sectional view illustrating the sensor according to the first embodiment. FIG. 2 is a cross-sectional view taken along line A1 - A2 of FIG. 1.
[0009] As shown in FIGS. 1 and 2, the sensor 110 according to the embodiment includes a base 50S, a support portion 10S, and a first member 10M.
[0010] As shown in FIG. 2, the support portion 10S is fixed to the base 50S. The first member 10M is supported by the support portion 10S. A gap g1 is provided between the base 50S and a part of the first member 10M. At least a part of the first member 10M is preferably conductive.
[0011] The first direction D1 from the base body 50S to the support portion 10S is the Z-axis direction. One direction perpendicular to the Z-axis direction is the X-axis direction. The direction perpendicular to the Z-axis direction and the X-axis direction is the Y-axis direction.
[0012] As shown in FIG. 1, the first member 10M includes a supported region 10Ms, a first movable region 10Ma, a first structure 21, a first support structure 11S, a first connection structure 21c, a first connection portion 11c, and a first beam 31.
[0013] As shown in FIG. 2, the support portion 10S is between the base body 50S and the supported region 10Ms in the first direction D1.
[0014] The first beam 31 extends along a second direction D2. The second direction D2 intersects the first direction D1. The second direction D2 is, for example, the X-axis direction.
[0015] The first beam position of the first beam 31 in the second direction D2 is between the first movable region position of the first movable region 10Ma in the second direction D2 and the support portion position of the support portion 10S in the second direction D2.
[0016] The first end 31e of the first beam 31 is connected to the first connection structure 21c. The first other end 31f of the first beam 31 is connected to the supported region 10Ms.
[0017] The first structure position of the first structure 21 in the second direction D2 is between the first movable region position (the position of the first movable region 10Ma in the second direction D2) and the first beam position (the position of the first beam 31 in the second direction D2). The first connection structure position of the first connection structure 21c in the second direction D2 is between the first structure position and the first beam position. The first support structure position of the first support structure 11S in the second direction D2 is between the first structure position and the support portion position.
[0018] The first structure 21 includes a first portion 21e, a first other portion 21f, and a first intermediate portion 21m. The third direction D3 from the first portion 21e to the first other portion 21f intersects a plane including the first direction D1 and the second direction D2. The first intermediate portion 21m is between the first portion 21e and the first other portion 21f.
[0019] The first portion 21e is connected to the first connection structure 21c. The first other portion 21f is connected to the first movable region 10Ma. The first intermediate portion 21m is connected to the first support structure 11S.
[0020] For example, the first member 10M includes a first portion connection part 21ec, a first other portion connection part 21fc, and a first intermediate portion connection part 21mc. The first portion connection part 21ec connects the first portion 21e to the first connection structure 21c. The first other portion connection part 21fc connects the first other portion 21f to the first movable region 10Ma. The first intermediate portion connection part 21mc connects the first intermediate portion 21m to the first support structure 11S.
[0021] The first connection part 11c connects the first connection structure 21c to the first support structure 11S.
[0022] For example, the first member 10M can move along the X-axis direction. In response to an external force, for example, the first movable region 10Ma moves along the X-axis direction. The movement of the first movable region 10Ma is transmitted to the first connection structure 21c by the first structure 21. The first structure 21 is, for example, a lever. The first portion 21e is, for example, the point of application. The first other portion 21f is, for example, the point of force. The first intermediate portion 21m is, for example, the fulcrum.
[0023] For example, a stress along the X-axis direction is applied to the first connection structure 21c. As a result, a compressive stress or a tensile stress is applied to the first beam 31. As will be described later, the first beam 31 vibrates when an alternating current signal is applied. The resonance frequency of the first beam 31 changes according to the stress applied to the first beam 31. By detecting the change in the resonance frequency of the first beam 31, an external force (for example, acceleration) applied can be detected.
[0024] In an embodiment, the first connection structure 21c is connected to the first support structure 11S by the first connection portion 11c. As a result, compared with a reference example in which the first connection structure 21c is not connected to the first support structure 11S, the movement of the first connection structure 21c becomes stable. Thereby, compared with the reference example, stable detection becomes possible. A sensor capable of improving detection accuracy can be provided.
[0025] As shown in FIG. 1, in this example, the first member 10M includes a second structure 22, a second support structure 12S, and a second connection portion 12c.

[0027] The second structure 22 includes a second portion 22e, a second other portion 22f, and a second intermediate portion 22m. The direction from the second other portion 22f to the second portion 22e is along the third direction D3. The second intermediate portion 22m is between the second other portion 22f and the second portion 22e. The second portion 22e is connected to the first connection structure 21c. The second other portion 22f is connected to the first movable region 10Ma. The second intermediate portion 22m is connected to the second support structure 12S.
[0028] For example, the first member 10M includes a second portion connection portion 22ec, a second other portion connection portion 22fc, and a second intermediate portion connection portion 22mc. The second portion connection portion 22ec connects the second portion 22e to the first connection structure 21c. The second other portion connection portion 22fc connects the second other portion 22f to the first movable region 10Ma. The second intermediate portion connection portion 22mc connects the second intermediate portion 22m to the second support structure 12S.
[0029] The second connection portion 12c connects the first connection structure 21c to the second support structure 12S. By connecting the first connection structure 21c to the second support structure 12S, the first connection structure 21c becomes stable.
[0030] In the third direction D3, the first connection structure 21c is between at least a part of the second support structure 12S and at least a part of the first support structure 11S. In the third direction D3, the first connection portion 11c is between the first connection structure 21c and at least a part of the first support structure 11S. In the third direction D3, the second connection portion 12c is between at least a part of the second support structure 12S and the first connection structure 21c.
[0031] For example, the movement of the first movable region 10Ma is transmitted to the first connection structure 21c by the second structure 22. The second structure 22 is, for example, a lever. The second part 22e is, for example, the point of application. The second other part 22f is, for example, the force point. The second intermediate part 22m is, for example, the fulcrum.

The second beam position of the second beam 32 in the second direction D2 is between the support portion position and the second movable region position of the second movable region 10Mb in the second direction D2. The second end 32e of the second beam 32 is connected to the second connection structure 22c. The second other end 32f of the second beam 32 is connected to the supported region 10Ms.

[0043] For example, the first member 10M includes a fourth portion connection portion 24ec, a fourth other portion connection portion 24fc, and a fourth intermediate portion connection portion 24mc. The fourth portion connection portion 24ec connects the fourth portion 24e to the second connection structure 22c.
