Abstract

An inductor in which when transparently viewed in an axis-line direction of a coil, a center position of a long via conductor in a width direction, which is a direction orthogonal to a longitudinal direction of the long via conductor, is deviated from a center position in the width direction of a first pad portion which is one of the pad portions and connected to the long via conductor.

Claims (45)

1 . An inductor comprising:

a component main body including a non-conductive material; and

a coil inside the component main body, the coil having a plurality of line conductors and a plurality of via conductors, each line conductor extending along a principal surface of the component main body, each via conductor extending perpendicularly to the principal surface of the component main body, each line conductor having a pad portion connected to a respective one of the via conductors, the coil having a helical orbit formed by the line conductors and the via conductors being connected together, wherein

the plurality of via conductors include a long via conductor that, when transparently viewed in an axis-line direction of the coil, has an elongated shape with a length dimension that is longer than a width dimension, the length dimension extending in a longitudinal direction of the long via conductor that follows the helical orbit of the coil, the width dimension extending in a width direction of the long via conductor that is orthogonal to the longitudinal direction of the long via conductor, and

when transparently viewed in the axis-line direction of the coil, a center position of the long via conductor in the width direction of the long via conductor is deviated, in the width direction of the long via conductor, from a center position in a width direction of the respective pad portion connected to the long via conductor, the width direction of the respective pad portion being orthogonal to the longitudinal direction of the long via conductor.

2 . The inductor according to claim 1 , wherein

the center position of the long via conductor is deviated to an outer peripheral side of the helical orbit.
