ABSTRACT:
To separate resin molded parts that are used for a push button switch member with less light leakage from the side faces and less trouble in key operation, easily, a resin molded body comprises one or more resin molded parts for a push button switch member, a frame surrounding the outside of the resin molded parts, one or more gates connecting a plurality of the resin molded parts each other or the resin molded part to the frame and one or more runners crossing the longitudinal direction of the gates, wherein the gates are connected at the back faces of the resin molded parts not to be coated with light shielding paint, and wherein the runners are connected to the gates on the same surfaces as the resin molded parts are connected to and are connecting the opposing sides of the frame.
