PURPOSE: To surely and firmly attach a protective cover body to a circuit board, in an LED array head where a semiconductor chip for light emission where many light emitting elements are made and a semiconductor chip for its control are mounted on the topside of a circuit board, and a protective cover body made of synthetic resin to cover the whole of the semiconductor chip for light emission and the semiconductor chip for control is installed. CONSTITUTION: Pins 6, which are arranged to be calked and transformed at the rear of a circuit board after being inserted into the pin holes 9 bored in the circuit board 1, are are provided at the sections near the four corners of the bottom of a protective cover 5, while reinforcing parts 7 are molded integrally so that the two pins are coupled with each other with reinforcing parts 7, at the two side faces opposed to each other of the protective cover 5. |
