Summary:To provide a coil component containing metallic particles with high filling factor, in which discriminability of the terminal electrode and the magnetic substance surface is improved.SOLUTION: A coil component 1 has a magnetic substance 10, a coil part, and terminal electrodes 21, 22. The magnetic substance contains at least hardened resin and metal particles, where the metal particles occupy 85 vol% or more, and the lightness on the surface of the magnetic substance, in the L*a*b* colorimetric system defined in JISZ8730, is 30-50. The coil part is formed in the magnetic substance and/or on the surface thereof, and the terminal electrodes 21, 22 are formed on the surfaces 11, 12 of the magnetic substance and electrically connected the coil part.SELECTED DRAWING: Figure 1 【課題】金属粒子を高い充填率で含み、端子電極と磁性体表面との識別性を向上させるコイル部品の提供する。【解決手段】コイル部品1は、磁性体10とコイル部と端子電極21、22とを有する。磁性体は、硬化した樹脂と金属粒子とを少なくとも含み、85vol%以上を金属粒子が占め、JISZ8730に規定されるL*a*b*表色系における磁性体の表面の明度が30〜50である。コイル部は、磁性体の内部及び/又は表面に形成されていて、端子電極21、22は磁性体の表面11、12に形成されコイル部と電気的に接続されている。【選択図】図1
