An inductor component includes cores, a coil disposed in the cores, and terminal electrodes. The coil includes first metal plates disposed on an upper surface of the cores, second metal plates disposed on a lower surface of the cores, and a plurality of metal pins each passing through one of the cores in a thickness direction. The coil has a helical shape by connecting the first metal plates to the second metal plates, with the plurality of metal pins therebetween. The terminal electrodes are spaced apart along a direction in which the helical shape extends, and are connected to the coil.

Inductor component and power supply module

An inductor includes a first terminal and a second terminal, a first inductor conductor layer and a second inductor conductor layer, a magnetic core layer, and via conductors. The magnetic core layer is disposed between the first and second inductor conductor layers. The via conductors are connected to the first and second inductor conductor layers. The first and second terminals are electrically connected through the via conductors. The magnetic core layer includes a first magnetic substance portion including a first magnetic substance, and a second magnetic substance portion including a second magnetic substance. Magnetic properties of the second magnetic substance are different from magnetic properties of the first magnetic substance.

Inductor and DC-DC converter

An inductor componentincludes a resin layerand an inductor electrode. The inductor electrodeincludes metal pinstothat extend in the resin layerwith upper end surfaces thereof exposed from the upper surfaceof the resin layer, and upper wiring platesandthat are disposed on the upper surfaceof the resin layerand that connect upper end surfaces of the short metal pinsandand upper end surfaces of the long metal pinsandto each other. In this case, the inductor electrodeis formed of the metal pinstoand wiring platestothat each have a specific electrical resistance lower than that of a conductive paste and plating, and the resistance of the entire inductor electrodecan be decreased.
