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.
