Abstract
A method for manufacturing a resin mold includes the steps of: attaching a transmitting resin member capable of transmitting a laser beam and an absorbing resin member capable of absorbing the laser beam; and irradiating the laser beam on an interface between the transmitting resin member and the absorbing resin member from a surface of the transmitting resin member so that a welding spot is formed on the interface and the transmitting resin member and the absorbing resin member are welded. The laser beam is irradiated homogeneously on the interface by a homogenizer so that a center portion of the welding spot and an outer portion of the welding spot are heated homogeneously by the laser beam.
