PROCESS FOR PRODUCING COIL COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a process for producing a coil component in which a copper plating layer at the coil part is prevented from being exposed to the surface of the exterior part 8. SOLUTION: The process for producing a coil component comprises a step for forming the copper plating layer 2 on a prismatic element body 1, a step for forming the coil part 3 composed of a linear part 3a and a groove part 3b formed by grooving the copper plating layer 2 spirally, a step for forming the exterior part 8 on the coil part 3, and a step for forming an electrode part 9, wherein a step for forming an insulation coating layer 4 between the copper plating layer 2 and the exterior part 8 is provided between the step for forming the coil part 3 and the step forming the exterior part 8.
