Reactor

Abstract

To provide a reactor with high heat dissipation.SOLUTION: A reactor 10 comprises: a reactor main body 1; a case 8 housing the reactor main body 1; and a filling molding part 9 that is formed into the case 8, and embeds the reactor main body 1, and includes a bus bar 54 that is connected to a leading wire 42 of a coil 4. The case 8 includes: a bottom surface; side walls 81, 82, 83, and 84 that are stood from the edge of the bottom surface; a concave part 811 of which the upper end of the side wall 81 is cut; and a case mold resin 6 that is provided to the concave part 811. The case mold resin 6 includes: a bottom surface part that is contacted to the upper surface of the side wall 81 of the concave part 811; and a wall part 62 that is stood from the edge of the bottom surface part 61, and is contacted to the side walls 81 and 84. A space surrounded by the bottom wall and the wall part of the case 8, and the wall part of the case mold resin becomes a housing space of the reactor main body. The bus bar 54 includes an embedded part 541 that is arranged to the upper direction of the bottom surface part, and is embedded in the filling mold part 9.SELECTED DRAWING: Figure 1
