PROBLEM TO BE SOLVED: To provide small-sized coil component having high electrical performance. SOLUTION: In the coil 1, provided with a bobbin 2 having a cylindrical section 2a around which a coil 3 can be wound and a first core section 5, in which an inner magnetic path section 5a positioned in the internal space of the cylindrical section 2a and an outer magnetic path section 5b positioned on the outer periphery of the bobbin 2, are formed integrally by laminating sheet cores 6 upon another, a second core section 8 having no inner magnetic path section is formed by laminating a plurality of sheet cores 7 upon another on the outer magnetic path section 5b of the first core section 5.
