The porous metal heat sink 106 is disposed on the second surface S2 and has a plurality of holes 112 communicating with each other. Since the porous metal heat sink 106 has a plurality of holes 112 communicating with each other, the heat dissipation area and the convection effect can be effectively increased, thereby improving the heat dissipation effect. Further, since the porous metal heat sink 106 is a porous structure as compared with the conventional heat sink, it has a light weight. The material of the porous metal heat sink 106 is, for example, a porous metal material. The porous metal material may be made of a metal or an alloy thereof, and the metal used is, for example, aluminum or copper.

The waterproof gas permeable membrane 114 is disposed on the outer surface of the porous metal heat sink 106. Since the waterproof gas permeable membrane 114 has water repellency and gas permeability, not only the components covered by the waterproof gas permeable membrane 114 (for example, the power source 118) can be waterproof, but the porous metal heat sink 106 can also retain the heat dissipation effect. The material of the waterproof gas permeable membrane 114 is, for example, polytetrafluoroethylene (PTFE).

The heat dissipation fins 116 are disposed on the second surface S2 and can be used for heat dissipation. The heat dissipation fins 116 can be in contact with the porous metal heat sink 106 to enhance the heat dissipation effect.
