    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 (3a) and groove (3b), 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 (1a) 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).
