PROBLEM TO BE SOLVED: To eliminate waste in rubber button material and to reduce the number of coating procedures of contact conductive material on a backside of a push button in a remote control device using a push button input device. SOLUTION: Two-piece compound unit 20 integrating two rubber buttons 10 consisting of a plurality of push buttons 11 is formed by pouring the melted rubber material into a metal mold. The two-piece compound unit 20 is formed integrally by having the push buttons 11 on the two rubber buttons 10, in a state where the arrangement is rotated 180°from each other and having each installed alternately between the push buttons 11. The contact conductive material is printed on the backside of the two-piece compound unit 20 and after that, the two-piece compound unit 20 is cut apart along a cutting line L. Thus, two rubber buttons 10 constituted by having the plurality of push buttons 11 arranged in a matrix and a plurality of connecting parts in the direction of the rows and bridges connecting one end of the connecting parts is obtained.
