Coil part and method of producing the same

摘要

A coil component of the present invention has prismatic base body ( 1 ), copper plated layer ( 2 ) formed on the outer periphery of base body ( 1 ), coil section ( 3 ) that is formed by spirally grooving copper plated layer ( 2 ) and has linear section ( 3 a) and groove ( 3 b), exterior section ( 8 ) formed on coil section ( 3 ), and electrode section ( 9 ). Insulating coating layer ( 4 ) is disposed between copper plated layer ( 2 ) formed on the outer periphery of longitudinal section ( 1 a) of base body ( 1 ) and exterior section ( 8 ). The copper plated layer of the coil section can be suppressed from being exposed at the surface of exterior section ( 8 ).
