Coil component

A coil component comprising:

• a substrate;
• a coil provided on a main surface of the substrate by plating and having a winding part having a uniform reference surface height with the main surface of the substrate as a reference surface;
• a resin body provided on a main surface of the substrate and having a plurality of resin walls, the winding part of the coil extends between the plurality of resin walls;
• a resin film integrally covering an upper surface of the coil and an upper surface of the resin body;
• and
• a coating resin made of magnetic powder-containing resin, the coating resin integrally covers the coil, the resin body, and the resin film provided on the main surface of the substrate;
• wherein the plurality of resin walls arranged on the main surface of the substrate include an outermost wall located at an outermost position, an innermost wall located at an innermost position, and an inter-wire wall interposed between the winding part of the coil;
• wherein, in at least one of the outermost wall and the innermost wall, the maximum reference surface height of the entire wall is equal to or less than the reference surface height of the winding part of the coil, and the reference surface height of a second side surface opposite to a first side surface in contact with the winding part of the coil is lower than the reference surface height of the winding part of the coil.
