PROBLEM TO BE SOLVED: To provide a reactor capable of preventing exfoliation on an interface between a case and a core and a crack of the core. SOLUTION: The reactor 1 has a coil-integrated core 10 including a coil 11 for generating a magnetic flux by power supplied and a core 12 made of magnetic powder mixed resin formed inside and on an outer periphery of the coil 11 to be hardened, wherein the coil 11 and the core 12 are integrated. The coil-integrated core 10 is accommodated inside the case 2 having an opening surface 21 on one surface. A groove 200 is formed on an inner side face 20 of the case 2. Resin 3 is filled between the coil-integrated core 10 and the case 2. COPYRIGHT: (C)2009,JPO&INPIT
