<p>PURPOSE:To provide a molding device for releasing surely a resin base after molding the resin base and the releasing method thereof. CONSTITUTION:A mold device comprises a stamper 2, an inner periphery presser 3 for fixing the stamper 2, first and second molds 1 split into two, a heater for heating resin and a means of flowing heated resin into the first and second molds 1, and a flow inlet 8 for gas is formed on a section where the stamper 2 is not in touch with on the face of a mold 1 with which the stamper 2 is brought into contact, and gap is allowed to flow in from said flow inlet 8 at the time of releasing so that the resin base can be released securely from the stamper 2 even when static is generated by friction at the time of molding the resin base.</p> |
