An inductor (100) includes a pair of magnetic members (cores (10, 20)), a main body having coils (71, 72), and a sheet-formed fixation member (60), wherein the fixation member (60) is bound across the cores (10, 20) and the main body, to thereby fix the cores (10, 20) which configure a closed magnetic path, and to thereby fix at least one of the cores (10, 20) to the main body.
