あった。However, since the conventional electric junction box uses screw fasteners to connect the heat pipe to the vehicle body as described above, the cost of parts is reduced (for example, caulking, soldering). Etc.) There has been a problem that processing costs and the like are increased and costs are increased. In addition, since the screw fastener is an inclusion between the heat pipe and the vehicle body, there has been a problem that the heat conduction efficiency is reduced as compared with the direct connection. Further, since the heat pipe is exposed between the electric connection box and the screw fastener and is not protected from external stress, the heat pipe may be damaged or deformed by an external force or the like applied during the mounting operation.

る。[0006] Since one end or both ends of the heat pipe held by the heat pipe protection portion are in direct contact with the heat radiating portion, at least a part of the surface of the heat pipe is exposed to the outside of the electric junction box. Is preferred. Thus, in the structure in which the heat pipe protection portion is formed on the mounting bracket portion of the electric connection box, and the heat pipe is held by the heat pipe protection portion, when the electric connection box is fixed to the vehicle body or the like, the mounting portion is used. By fixing the bracket portion with a bolt or the like, the heat pipe and the vehicle body are brought into close contact with each other, and the heat conductivity from the heat pipe to the vehicle body or the like is improved. Therefore, the heat obtained from the heat absorbing portion of the heat pipe provided inside the electric junction box having the heat source can be radiated to the vehicle body from the heat radiating portion of the heat pipe at low cost and efficiency.
