In a terminal temporary holding structure, a terminal fitting includes a cable connecting part, an electrical contact part fastened to the busbar terminal, and a connecting part connecting the electrical contact part and the cable connecting part. A terminal step part is formed in the terminal fitting at a position at which the connecting part and the electrical contact part are connected to each other. A housing in this structure includes a drop-in recess accommodating the electrical contact part and a suppressing part disposed over the cable connecting part and/or the cable. An engagement step part configured to engage to the terminal step part is formed in a step of a periphery of the drop-in recess so as to temporarily hold the terminal fitting in cooperation with the suppressing part before the electrical contact part is fastened to the busbar terminal by the fastening member.
