Abstract

In a built-in coil substrate, coil conductor patterns are provided on insulating base materials. Coil interlayer connection conductors, which provide interlayer connection between the coil conductor patterns, are provided on the insulating base materials and made of conductive paste. First and second external electrodes are provided on a first principal surface of a multilayer body. One of the coil conductor patterns is connected to the first external electrode by first-external-electrode connection conductors made of the conductive paste. Another one of the coil conductor patterns is connected to the second external electrode by a second-external-electrode connection conductor. The second-external-electrode connection conductor is a metal film provided in a through hole that extends through the multilayer body in a stacking direction in which the insulating base materials are stacked.
