ELECTRICAL JUNCTION BOX

WIPO Patent Application WO/2022/264814

A1

The purpose of the present invention is to provide a technique with which, while a waterproof resin filled in a through-hole in a flowable state hardens and becomes an unflowable state, the waterproof resin can steadily stay in the through-hole. This electrical junction box comprises: a bus bar; a molded resin portion that is insert-molded using the bus bar as an insert component; a case that covers the molded resin portion to form a waterproof space; a filling portion that fills a first opening portion of a through-hole formed so as to pass through the molded resin portion; and a waterproof resin that is filled in the through-hole. The through-hole is formed between a first holding portion and a second holding portion so as to expose the entire circumference of the intermediate portion of the bus bar. The filling portion is a member provided in addition to the molded resin portion. The waterproof resin reaches the filling portion while covering the entire circumference of the intermediate portion of the bus bar.
