PURPOSE:To provide a production method of rigid/flexible board by which it is enough flexible to be bent partially without corroding or contaminating the part of flexible board. CONSTITUTION:The titled production method consists of the following processes: First, a rigid board 20 made of glass epoxy, etc., is prepared in such a way that copper foil is provided on one surface of it and at least conductor circuit 21 is provided on the part to form a groove that will become a window opening section 30 on another surface. Next, laser beam is applied on the board 20 to form a groove. Then the substrate 20 is piled up on a flexible substrate 10 in which the circuit 21 is formed, setting the groove inwardly, so as to form the circuit 21 on the rigid board. Finally, the board 20 is peeled off along the groove in order to form the section 30. |
