Abstract
An electronic component includes a stack and first and second inductors. The first inductor includes a first through hole column, a second through hole column, a first conductor layer portion, a second conductor layer portion, and a third conductor layer portion. The second conductor layer portion is connected to an end of the first through hole column and extends close to the second through hole column. The third conductor layer portion is connected to the second through hole column and extends close to the first through hole column.
