To provide a method for mounting electric parts on both surfaces of a substrate. The electric parts (32, 33) on the front and rear surfaces of the substrate (31) are simultaneously pressed by first and second pressing rubbers (15, 25). Therefore, the electric parts (32, 33) can be connected to the front and rear surfaces of the substrate (31) at a time. When the first and second pressing rubbers (15, 25) are deformed, the first and second rubbers (15, 25) are so interrupted by a dam member (16) as to be not expanded, since the peripheral areas of the pressing rubbers are surrounded by the dam member (16). Therefore, the electric parts (32, 33) are not displaced. Since the electric parts (32, 33) are connected to the substrate (31) at the same positions as in a temporary pressure bonding, an electric part (30a) with high connection reliability can be provided. |
