    摘要： [Problem] To provide a core for a coil component having a structure in which a direct current superimposition characteristic can be improved by means of a technique other than lowering an effective relative magnetic permeability.
    [Solution] A coil component core 10 is the coil component core 10 that is configured by having a plurality of core pieces that are connected in an annular shape. With respect to each of the plurality of core pierces, when a length in a magnetic path direction is I and a cross-sectional area that is perpendicular to the magnetic path direction is S, I/S is equal to or less than 1.0. The direct current superimposition characteristic of the coil component is significantly improved by using this configuration.
