Patent attributes
Provided is an electrical junction box that has a novel structure capable of stably preventing water from intruding into a case while simplifying the operation for connecting the electrical junction box and an external apparatus. An electrical junction box includes a circuit structure that includes a connection terminal for connection to an external apparatus, a case that has an insertion hole and houses the circuit structure, a relay terminal that is connected to the connection terminal, and includes an external connection portion that is inserted into the insertion hole and is exposed to the outside of the case, and a sealing member that is compressed between opposing surfaces of the insertion hole and the relay terminal and seals the insertion hole.
