In the hot water supply device, generally, the front cover and the case of the hot water supply device body are made of metal, and the respective surfaces of the front cover and the case of the hot water supply device body are respectively subjected to insulation coating.
When the metal portion of the front cover 101 is thin or the front cover 101 is coated inside the hole 104 for inserting the conductive screw 103, the front cover 101 and the hot water supply apparatus main body 102 cannot be electrically connected to each other by the screw-threaded portion of the conductive screw 103 and the front cover 101. Therefore, in the present embodiment, the head 201 of the conductive screw 103 preferably has a coating scraped portion 203. As shown in fig. 2 and 3, the conductive screw 103 includes a head 201 and a tooth 202, and a coating-scraped portion 203 is provided on a surface of the head 201.
