<P>PROBLEM TO BE SOLVED: To obtain a reactor which inhibits the deformation of a heat transmission sheet, improves an adhesion force between the heat transmission sheet and a coil, and increases a heat radiation area thereby maintaining high heat radiation performance and achieving excellent durability. <P>SOLUTION: A reactor 50 includes: a reactor body 10 where a bobbin 4 is formed around a reactor core 1 and a coil 5 is formed around the bobbin 4; a case 20 formed by at least a bottom plate 11; and a heat transmission sheet 30 disposed between at least the coil 5 of the reactor body 10 and the bottom plate 11 of the case 20. The heat transmission sheet 30 has an upper surface 30a contacting with the coil 5; a lower surface 30c contacting with a surface 13a of a recessed part 13 of the bottom plate 11 which faces the coil 5; and a side surface 30b connecting the upper surface 30a with the lower surface 30c. The bottom plate 11 has a contact surface 13b contacting with the side surface 30b of the heat transmission sheet 30. <P>COPYRIGHT: (C)2013,JPO&INPIT |
