Abstract

A coil component has a pair of flange portions including a bottom surface that may be mounted on a mounting substrate and a top surface opposite to the bottom surface, a winding core portion coupling the pair of the flange portions, a top plate attached to the top surface of the flange portions, a metal terminal attached to each of the flange portions, and a wire wound around the winding core portion and electrically connected to the metal terminal. The metal terminal has a wire connecting portion connected to the wire and a flange connecting portion connected to the flange portion, and the wire connecting portion and the flange connecting portion are each located on the top surface side of a peripheral surface positioned between the bottom surface and the top surface of the flange portion.

Description

technical field [0001] The present invention relates to coil components. Background technique [0002] Conventionally, as a coil component, there is a coil component described in Japanese Patent No. 5156076 (Patent Document 1). The coil component has: a pair of flanges including a bottom surface capable of being mounted on a mounting substrate and a top surface opposite to the bottom surface; a winding core connecting the pair of flanges; a metal A terminal, the metal terminal is attached to the bottom surface side of the flange portion; a top plate, the top plate is attached to the top surface of the flange portion; and a lead wire is wound around the core portion and electrically connected to the metal terminal. The wire is connected to the metal terminal by welding, and the welding part is located in the concave part provided on the bottom surface. [0003] Patent Document 1: Japanese Patent No. 5156076 [0004] However, in the above conventional coil component, since ...
