PROBLEM TO BE SOLVED: To provide a wiring appliance plate, in which a metal plate can be attached easily to a middle plate and which enables improvement of a work efficiency in a manufacturing process. SOLUTION: Respectively four attachment tabs 32 are made to protrude from the rear sides of both side parts 30a in a short width direction of a metal plate 30 with approximately the same intervals. Protruding retainers 33 are made to protrude from the inner side surfaces of the respective attachment tabs 32. The tip parts of both the side parts 30a of the metal plate 30 are inserted into insertion grooves 28 formed in both the sidewalls 23 of a middle plate 20. If the attachment tabs 32 are pushed into the middle plate 20, retaining tabs 29 on the inner sidewalls 23 of the middle plate 20 are bent due to the pressures of the retainers 33 and the tips of the retaining tabs 29, and finally, the retainers 33 retain each other and the metal plate 30 is mated with a mating recess in the front surface of the middle plate 20, and furthermore are fixed through the retainment of the retainers 33 and retaining tabs 29 (fall-off proof). Thus, the metal plate 30 can be attached easily to the middle plate 20, and working efficiency in a manufacturing process can be improved.
