Abstract

In a planar coil element, since an overlapping portion of a fourth resin wall of a first conductor pattern protrudes from an end surface of a main body portion, restriction on a width of the overlapping portion is relaxed, and the wide overlapping portion is realized. Therefore, an improvement in a withstand voltage between the second external terminal electrode formed on the end surface and an outermost turn of the first conductor pattern is realized. Similarly, regarding the second conductor pattern, the improvement in the withstand voltage between the first external terminal electrode formed on the end surface and an outermost turn of the second conductor pattern is realized.
