An electrical connection box includes first insertion lock mechanisms and second insertion lock mechanisms. The first insertion lock mechanisms include respective first insertion locking pieces and respective first insertion receivers, and serve as rotation fulcrums of relative rotation of a lower cover and a frame in a state in which the respective first insertion locking pieces are inserted into the respective first insertion receivers and the respective first insertion locking pieces are not locked in the respective first insertion receivers. The second insertion lock mechanisms include second insertion locking pieces and second insertion receivers, guide the second insertion locking pieces with the second insertion receivers in a state in which the first insertion lock mechanisms serve as the rotation fulcrums, and determine the relative positions of the frame and the lower cover.
