<p>PROBLEM TO BE SOLVED: To provide a laminated coil component having high current characteristics and mechanical strength, in which plating elongation is less likely to occur, and an alloy is used as a magnetic material.SOLUTION: A laminated coil component 1 has a coil formation region, and two cover layers sandwiching the coil formation region vertically, the coil formation region has a magnetic material 12 formed of alloy-based particles and a coil-like conductor 11 embedded in the magnetic material 12, at least one of the two cover layers has an inner layer 21 in contact with the coil formation region, an outer layer 23 located on the outermost side, and an intermediate layer 22 sandwiched by the inner layer 21 and outer layer 23. The outer layer 23, inner layer 21 and intermediate layer 22 are formed of alloy-based particles, and the average grain size of the alloy-based particles in the intermediate layer 22 is larger than that of the alloy-based particles in the outer layer 23.</p> |
