ABSTRACT:
A layered coil, having high connection reliability, formed by alternately stacking a plurality of coil conductors and insulators. Outlet portions of the of coil conductors are connected with each other without using through holes. The coil conductors are formed on surfaces of insulating sheets so that the outlet portions of the coil conductors project from edges of the insulating sheets. The insulating sheets are stacked so that the outlet portions of the coil conductors can be connected, by spot welding or the like, with each other or with terminals in portions projecting from surfaces of the layered product.
