Zusammenfassung:	To provide a coil component which has an improved coil withstand voltage and improved burr on an exposed surface of an external terminal, and which allows improvement in DC resistance (Rdc) characteristics and scattering.SOLUTION: A coil component includes: a main body; a coil disposed in the main body; and an insulating film which covers at least part of the coil inside the main body. The insulating film contains a copolymer which contains: a repeating unit derived from a monomer including an unsaturated bond; and a repeating unit derived from a parylene monomer.SELECTED DRAWING: Figure 3 【課題】コイル耐電圧が向上し、外部端子の露出面のバリ（ｂｕｒｒ）が改善され、直流抵抗（Ｒｄｃ）特性及び散布向上が可能なコイル部品を提供する。【解決手段】本開示は、本体と、上記本体内に配置されるコイルと、上記本体内で上記コイルの少なくとも一部を覆う絶縁膜と、を含み、上記絶縁膜は、不飽和結合を含む単量体から誘導された繰り返し単位及びパリレン単量体から誘導された繰り返し単位を含む共重合体を含む、コイル部品に関するものである。【選択図】図３
