PROBLEM TO BE SOLVED: To provide a push-button and its manufacturing method, with which sufficient touch of hardness of the push-button is obtained, manufacturing process is simplified, productivity is improved and manufacturing at low-cost is realized. SOLUTION: The manufacturing method of the push-button is composed of a printing process of printing all or a part of symbols used for the push- button on the reverse side of specified positions on a synthetic resin film, which is transparent or can be seen through, an impasto printing process for thick printing on the printed surface, after the above printing process, using a special ink for giving hardness to the push-buttons, a push-button body molding process in which the synthetic resin film is molded into a specified dish shape of a push-button body by hot pressing or the like, in such a way that the impasto printed part in the impasto printing process becomes the inside, and of a cast rubber molding process for integrally molding a rubber mat layer, by directly pouring rubber into the push-button main body molded in the push-button body molding process.
