PROBLEM TO BE SOLVED: To provide a coil integrated with core having a structure suitable for miniaturization of the whole. SOLUTION: A groove (2b) for introducing adhesive agent (4) into a gap between the outer surface of the core (1) and the inner surface of internal space (2a) of a bobbin (2) is formed on at least either of the outer surface of core (1) or the inner surface of internal space (2a) of the bobbin (2). A protrusion (2d) for protecting the projections of both ends of the core (1) projected from a flange (2c) is provided on the flange (2c), and the external surface of the flange (2c) is formed so as to have a protruded surface in a KAMABOKO (boiled fish-paste) shape. According to the method, the adhesive agent (4) is readily invaded into the deep place of the gap between the outer surface of core (1) and the inner surface of internal space (2a) of the bobbin (2). The protrusion (2d) protects the projected parts of both ends of the core (1). The outer surface of flange (2c) is the one protruded in the KAMABOKO shape whereby the thickness of the flange can be thickened and the strength of the flange is increased thereby making little occurrence of deformation such as warpage or the like. Accordingly, it becomes optimum for the miniaturization of the core integrally formed coil (10). COPYRIGHT: (C)2007,JPO&INPIT
