PROBLEM TO BE SOLVED: To provide a multi-molded wiring board that not only enables the location of each circuit board area in a previous matrix array to be detected absolutely even after a mother board is divided, but also enables the mounting of an electronic part or its mounting to an external electric circuit board to be normally conducted. SOLUTION: This multi-molded wiring board is composed of multiple laminated insulating layers. It is provided with a mother board 1 having a plurality of circuit board areas 2 arranged vertically and horizontally at the center of the principal plane and dummy areas 4 at the periphery, a wiring conductor 3 formed in the wiring board area 2, and a symbol pattern formed in the internal layer at the lower side of each circuit board area 2.
