ELECTRICAL CONNECTION BOX

摘要

This electrical connection box (10) comprises: a casing (11); and a relay (26A) that is housed inside the casing (11) and that includes a relay case (32) and a terminal part (33) housed in the relay case (32) and including a fixed contact point (FC) and a movable contact point (MC). Inside the casing (11) is formed a small-heat-generation-amount region (31) that has a smaller heat generation amount than the relay (26A) when a current is passed through the relay (26A). The relay (26A) is arranged in a posture such that the fixed contact point (FC) and the movable contact point (MC) are located on the side of the small-heat-generation-amount region (31).
