PROBLEM TO BE SOLVED: To provide a coil which has a small electric loss and small dimension. SOLUTION: In a coil having a core and turns which are arranged as conductor tracks on base layers, a plurality of the base layers 1 have at most one turn 2, respectively. The start part 3 and the end part 4 of the turn 2 are led out to one or a plurality of protruding parts 10 on the outer peripheral parts of the base layers 1, respectively. A plurality of the base layers 1 are mutually connected via the protruding parts 10. Thus the coil is constituted.
