PROBLEM TO BE SOLVED: To provide a small-sized laminated coil which can obtain good electrical characteristics. SOLUTION: A laminate is constituted by laminating insulating sheets 13 carrying printed coil conductor patterns 12 which constitute a spiral coil L2 and protective insulating sheets 14 upon another. Each coil conductor pattern 12 has a zero gap between its outer peripheral edge and the outer peripheral edge of the sheet 13. The coil conductor patterns 12 constitute a coil L2, in such a way that the patterns 12 are successively connected electrically to their adjacent coil conductor patterns 12 through via holes 27 formed at a corner section of the sheets 13.
