PURPOSE:To stably hold the interval between a plurality of wiring members at the time of injection molding even when the wiring members are set to up and down positional relation. CONSTITUTION:A primary molded product 7 holding at least one wiring members 3-5 is formed and used as a spacer to incorporate the wiring members 3-5 and other wiring members 3-5 in a mold to perform the three-dimensional insert molding of a wiring board holding the interval between a plurality of the wiring members 3-5. By this constitution, even when a plurality of the wiring members 3-4 become up and down positional relation, a position is decided by using the primary molded product as the spacer to enable insert molding and, therefore, even when a large number of the wiring members 3-4 are used, there is excellent effect such that the wiring board can be certainly molded without generating a deficient product. |
