PROBLEM TO BE SOLVED: To reduce the manufacturing cost of a wiring board by making efficient a process of forming a wiring pattern and forming the wiring pattern with high precision. SOLUTION: A method of manufacturing the wiring board in which when a wiring layer or an insulating layer is formed in a predetermined pattern, the resist pattern is formed by coating the surface of a workpiece with resist, exposing the resist to the predetermined pattern, and developing the resist employs a method of exposure using a glass mask and a method of drawing exposure using a laser beam in combination as the process of exposing the resist 15.
