A manufacturing method of a hardening pad using a transparent mold is provided to shorten a manufacturing process and setting time of a hardening pad without a manual work by forming an upper plate into a transparent mold. Synthetic resin is molded into the synthetic resin of a thin plate in which a key seat is imprinted through the mold for a key seat. Symbol, character or number is printed on the synthetic resin of the thin plate. The synthetic resin of the thin plate is molded into the key seat. The key seat is placed in a bottom plate(S100). The synthetic resin is put into the key seat(S110). An upper plate of the transparent material is imprinted to the same sectional shape as a sectional shape of a pad. The upper plate covers the key seat. The upper plate is pressurized with a roller(S130). The pad is molded into one plate in the single-side of the key seat. The synthetic resin pressurized in the key seat is hardened with ultraviolet irradiation(S150). The hardened key seat integrated pad exfoliates from the upper plate(S170).
