A jumper module mounting circuit board includes: a circuit board; and a jumper module having an insulator main body provided with conductive electrical connection parts for connecting between connection patterns so as to provide electrical continuity therebetween by connecting each of contact parts on both ends of the conductive electrical connection parts to the connection patterns which are formed to be spaced apart from each other on the circuit board. The jumper module is mounted onto the circuit board so as to connect between the contact parts and the connection patterns that are formed to be spaced apart from each other. The circuit board includes a connection pattern concentrated section that is formed by concentrating the connection patterns depending on a plurality of wiring specifications at a mount position of the jumper module.

An electrical junction box includes a bolt fixation portion made of resin, the bolt fixation portion having a bolt insertion hole through which a bolt is inserted to fix the electrical junction box to a vehicle. The bolt fixation portion includes a protrusion extending in an axial direction of the bolt in a state in which the bolt is inserted through the bolt insertion hole. The protrusion is configured to limit a rotationally movable range of an operating portion of a tool that is used in a state in which the operating portion extends in a direction intersecting the axial direction of the bolt.

A pin header includes a connection pins and a pin holder. The connection pins includes one end to be connected to a first circuit board and the other end to be connected to a second circuit board which is positioned to form a given gap between the first circuit board and the second circuit board. The pin holder includes a holder body which holds centers of side faces of the plurality of connection pins, and a projection holder which includes a first projecting portion projecting from the holder body toward a side of the one end of the connection pins, and a second projecting portion projecting from the holder body toward a side of the other end of the connection pins. A projection length of the first projecting portion is equal to a projection length of the second projecting portion.
