Abstract

The present invention provides a laminated electronic component that can suppress the occurrence of structural defects such as cracks and that includes a coil with a small DC resistance value. A laminated electronic component 100, which is laminated with insulator layers 100L0 to 100L27 and conductor patterns 100a, and connects the conductor patterns 100a between the insulator layers to form a coil within the laminate, is characterized by That is, the coil has a pair of conductor patterns, the pair of conductor patterns is composed of two conductor patterns (for example, conductor pattern 100L12a and conductor pattern 100L15a ) that are overlapped with an insulator layer sandwiched between them, the first connection part 100bc, the two conductor patterns The two ends are connected by the first connection part 100bc to connect two conductor patterns in parallel, the second connection part 100d, and the pairs of conductor patterns in multiple groups are connected in series by the second connection part 100d, and the coil patterns are connected to each other. The first connection part 100bc and the second connection part 100d are arranged at offset positions in the direction of the longer line.

Description

technical field [0001] The present invention relates to a laminated electronic component in which a circuit is formed inside a laminate in which an insulator layer and a conductor pattern are laminated. Background technique [0002] With the miniaturization and high performance of mobile devices, small multilayer power inductors are currently used as inductors for power supply circuits that function as DCDC converters. In recent years, there has been a trend toward larger currents, so inductor specifications with lower DC resistance characteristics are required. [0003] As a method of reducing the DC resistance, for example, there is a method of increasing the cross-sectional area of ​​the inner conductor and shortening the line length. However, if the width of the conductor is widened, the method of increasing the cross-sectional area leads to a decrease in the area through which the magnetic flux passes and a decrease in the inductance value. In addition, if the thickne...
