Abstract: A filter component assembly kit includes a bobbin that is configured with first and second members and a core that is in a quadrangular frame shape. When the first member is assembled with the second member, a through hole is formed in the bobbin. The through hole extends in a first direction. The core is configured with first and second extension bars. The first and second extension bars extend in parallel in the first direction. When the first extension bar is disposed in the through hole of the bobbin, rotation of the core around the first extension bar is prevented. First allowance of the first extension bar in a second direction, which is perpendicular to the first direction, in the through hole is larger than second allowance of the first extension bar in a third direction, which is perpendicular to the first and second directions, in the through hole.

Abstract: 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.

Abstract: A magnetic core (50) has a core shaft part which is inserted into a bobbin part, and configures a magnetic path of magnetic flux formed by a coil (40); the magnetic core (50) is configured by combining a pair of magnetic components (51, 52); the magnetic components (51, 52) have core ends formed so as to cross a core shaft part; the base part (20) has a fitting part which fits with at least one of the pair of core ends, when the core shaft part is inserted into the bobbin part; and the coil component (100) is characterized in that the pair of magnetic components (51, 52) and the bobbin base (10) are fixed to each other, while being bound by a sheet-like fixation member (70) which extends over the core end and the base part having been fitted to each other.
