摘要： A cooling fin 9 is joined to a semiconductor element 1. A resin 10 encapsulates the semiconductor element 1. A portion of the cooling fin 9 projects from a lower surface of the resin 10. A cooler 11 has an opening 12. The cooling fin 9 projecting from the resin 10 is inserted in the opening 12 of the cooler 11. The lower surface of the resin 10 and the cooler 11 are joined to each other by a joining material 13 such as an adhesive. Therefore, a reduction in the number of component parts and a reduction in weight can be achieved, and compatibility between the heat conductivity and the strength of joining can be ensured.

摘要： An outdoor unit for an air-conditioning apparatus, having a compressor, a top cover configured to cover an upper surface of the compressor, and a side cover configured to cover a side of the compressor and a side of the top cover, the side cover including a rectangular cutout portion formed in a part of an upper end of the side cover. The outdoor unit has a non-water-absorbent draining element disposed across from a central portion of the top cover to a bottom portion of the cutout portion, and tilts down from the central portion of the top cover toward the bottom portion of the cutout portion.
