Abstract
A coil component in which occurrence of plating elongation is further suppressed and an inductance value is higher. A coil component includes an element body including metal magnetic particles, a coil conductor inside the element body, and a plurality of external electrodes on a surface of the element body. The element body has a substantially rectangular parallelepiped shape including upper and lower surfaces substantially orthogonal to a winding axis of the coil conductor, first and second side surfaces facing each other, and third and fourth side surfaces facing each other. An average particle diameter of each of metal magnetic particles constituting the upper surface, metal magnetic particles constituting the lower surface, metal magnetic particles constituting the first side surface, and metal magnetic particles constituting the second side surface is smaller than an average particle diameter of metal magnetic particles existing inside a winding portion of the coil conductor.
