Abstract
A substrate ( ), a first mold ( ) and a second mold ( ) are prepared, and a plurality of switch patterns ( ), ( ) are provided by providing openings (pattern-removal portions) (A) in such a manner that a pattern ( ), which has been formed on the surface of the substrate ( ), is divided into a plurality of patterns to form A switch substrate. Next, the switch substrate ( ) is clamped between the first mold ( ) and the second mold ( ). At such time, the side of the switch substrate ( ) provided with the switch patterns ( ), ( ) is brought into surface contact with an abutting surface ( ) of the first mold ( ) and, at the same time, a cavity ( ) provided in the second mold ( ) opposes the other side of the switch substrate. Next, a molten molding resin is charged into the cavity ( ) provided in the second mold ( ) to thereby fill the cavity ( ) and the openings (A) of the substrate with the molding resin. After the molding resin hardens, the first mold ( ) and the second mold ( ) are separated and the switch substrate ( ), which will have the molding resin case attached thereto, is extracted.
