Abstract A cleaning device and a cleaning method for cleaning a resin sealing metal mold effective for removing complex stains on the metal mold in a short time, the stains containing organic and inorganic substances. The cleaning device decomposes stains on the inner part of the metal mold by irradiating the stains with a laser beam. The cleaning device comprises a laser beam generating means, a first reflection means for reflecting the laser beam generated by the laser beam generating means, and a second reflection means for receiving the reflected laser beam from the first reflection means in order to irradiate the inner part of the metal mold.
