Abstract
A wire coil component includes a shaped article, a wire wound around the shaped article, and terminal electrodes to which the ends of the wire are connected. The shaped article is formed from a magnetic resin containing a binder resin and a magnetic metal powder and has a thermal expansion coefficient of about 12 ppm/K or more and about 16 ppm/K or less (i.e., from about 12 ppm/K to about 16 ppm/K) from −55° C. to 150° C.
