PROBLEM TO BE SOLVED: To enable to remove a setscrew safely by insulating the setscrew which couples an output terminal and a connecting terminal from the output terminal. SOLUTION: A vehicular power supply device couples the output terminal 4 installed outside of a case 1 having a plurality of batteries 20 built in, and the connecting terminal 5 of the outer connector 2 by a coupler 3. The coupler 3 is provided with the setscrew 8 to be inserted through the laminated output terminal 4 and connecting terminal 5, a nut 9 to be screwed into this setscrew 8, and an insulating cover 10 to make insulation by covering surfaces of the output terminal 4 and the connecting terminal 5. The setscrew 8 makes a screw part as a metal screw 13 by insulating the head part. The setscrew 8 is inserted through the laminated output terminal 4 and connecting terminal 5, the nut 9 is screwed into the tip part, the output terminal 4 and the connecting terminal 5 are pinched, fixed, and coupled by the setscrew 8 and the nut 9, and the surfaces of the output terminal 4 and the connecting terminal 5 coupled by the setscrew 8 is covered and insulated by an insulating cover 10.
