a method manufactures a front panel including a front panel body formed of a single transmissive resin layer and a sensor film attached thereto , using a first mold having a molding recessed portion and a second mold having a molding projecting portion . the first and second molds are joined together such that a cavity is formed between the molding recessed portion and the molding projecting portion , by placing the sensor film between the first mold and the second mold , on the molding projecting portion in the cavity . a melted resin is injected into the cavity to form the single transmissive resin layer having a front surface formed in a shape of the molding recessed portion , and a back surface formed along the sensor film in a shape of the molding projecting portion , thereby laminating the sensor film to the back surface of the transmissive resin layer .
