Electrical junction box

An electrical junction box comprising:

• a busbar;
• a molded resin portion that is insert-molded using the busbar as an insert component, the molded resin portion having a first holding portion, a second holding portion and a through hole extending through the molded resin portion so as to define a first opening and a second opening, wherein the through hole is disposed between the first holding portion and the second holding portion;
• a case that covers the second holding portion of the molded resin portion to form a waterproof space;
• a blocking portion formed integral to the case and is configured to be inserted into the first opening of the through hole so as to block the first opening;
• and
• a waterproofing resin that fills in the second opening of the through hole and abuts against the blocking portion, wherein the waterproofing resin is closed by the blocking portion at the first opening and is exposed at the second opening,
• wherein the first holding portion holds one end portion of the busbar, and the second holding portion holds the busbar with the other end portion of the busbar being exposed in the waterproof space,
• an entire periphery of an intermediate portion of the busbar is exposed in the through hole and encased by the waterproofing resin,
• the blocking portion is a member that is provided separately from the molded resin portion, and
• the waterproofing resin reaches the blocking portion while entirely covering the periphery of the intermediate portion of the busbar.
