PURPOSE: To simplify the assembling operation by providing molded member pieces, which are to be formed into one body of predetermined shape while their engage parts arranged on their end planes are engaged, and circuit patterns which are formed at least on surfaces of said molded member pieces and composes a required wiring circuit by being connected electrically when said pieces are combinded into one body of predetermined shape.
CONSTITUTION: Molded member pieces 1 and 2 are combined into one body of predetermined shape by engaging engage parts 3 and 4 arranged on end planes 1a and 2a of said pieces 1 and 2 respectively. Circuit patterns 5a and 5b are formed at least on surfaces of the molded member pieces 1 and 2. When the pieces 1 and 2 are united into a predetermined shape, these are connected also electrically to compose a required wiring circuit. The circuit patterns 5a and 5b are laid so far as contact the planes of the engage parts 3 and 4 of the molded member pieces 1 and 2 in order to engage the molded member pieces 1 and 2 into one body. If necessary, ultrasonic wave is used to combine the engage parts and to connect them electrically, and a required wiring circuit is composed.
