PURPOSE: To create a wiring board quickly and easily by creating a specific wiring pattern using a computer and then printing a wiring pattern with original size on a flexible insulation member based on that information.

CONSTITUTION: A computer 11 is constituted of a body 11a, an input part 11b, and a display 11c and then the body 11a and a printer 12 which is a printing device are mutually connected. The computer 11 inputs data to the body 11a from the input part 11b while confirming the display 11c and creates the wiring pattern of a specific circuit, thus playing a role of a CAD system. Then, the information of the created wiring pattern is transmitted to a printer 12. The printer 12 prints a wiring pattern 13b with original size on a flexible insulation material 13a according to a conductive printing member and then delivers it as a wiring board 13. thus manufacturing the wiring board quickly and easily and at the same time verifying circuit operation easily.
