PURPOSE: To easily establish the connection by inserting both ends of two inductor elements provided facing each other through a substrate into the holes thereof.

CONSTITUTION: A square-spiral inductor element 5 consisting of copper plate and an inductor element 9 formed in the same shape as the inductor element 5 by printing a conductor paste to a substrate 8 are used, the terminals 6, 7 at both ends of inductor element 5 are bent and are inserted into the holes 10 of the substrate 8, and these are connected to the inductor element 9 as required. Upon alignment of the inductor element 5 and the inductor element 9, the terminals 6, 7 can be used as the through hole conductors.
