PURPOSE:To prevent a breakage of a connection part with operability improved and miniaturize an appliance by making a circuit unit with a circuit member and a terminal fitting with a screw preconnected, and mounting the unit on the given position in a case. CONSTITUTION:A power source transformer 9 is inserted in a case 8 after a lead wire of the transformer 9 is soldered to a lead wire connection part of a terminal fitting 1 with a screw. Then the fitting 1 connected with the lead wire is mounted on mounting parts 10 and 11 of the case 8, furthermore, holders 15 and 16 are inserted in the case 8, and are pressedly fixed with an opening part covered with a cover. And the primary side power source electric wire and the secondary side load electric wire are installed in the mounted fitting 1 with a terminal screw 3. This enables a breakage of a connection part to be prevented with operability improved and miniaturization with necessary space decreased by preconnecting the circuit member and the terminal fitting with the screw, and mounting them on the given position in the case.
