Abstract
Disclosed is an input device in which a control member is molded by injecting a liquid synthetic resin from an inlet of a mold formed at a position corresponding to the top of a control portion. The inlet is positioned at about the center of the control member, and the synthetic resin flows from the control portion having a relatively large thickness to beam portions and base portions that have a relatively small thickness. This allows smooth flow of the synthetic resin, and ensures consistently high quality and high precision of the control member. Moreover, fiber orientation is made uniform in the beam portions and the base portions, which gives good bending characteristics to the beam portions.
