Abstract
A vacuum forming method of forming a decorative film in close contact with a surface of an adherend in a forming space, by using a vacuum forming machine having the forming space seal-formed by a lower box and an upper box, includes: a pressure adjusting process of decompressing a lower division of the forming space sealed to have a lower pressure than an upper division of the forming space so as to produce a pressure difference between the divided forming spaces, thereby setting the pressure in the vicinity of the surface of the adherend lower pressure than that of the periphery thereof; a pressure releasing process of releasing the pressure difference after the forming process; and an extracting process of extracting a formed product. A lower end portion of the upper box is provided with a jig which suppresses lifting of the decorative film.
