Abstract: PURPOSE:To deep-form in uniform thickness without developing breakage and porousness by a method wherein fluororesin sheet, by which the recessed part of a forming mold member is covered and which is pressurized with a keep ring and heated, is fabricated as being slid on the forming mold member by suckingly discharging the air in the recessed part. CONSTITUTION:Fluororesin sheet 13, onto which a keep ring 14 is placed, is put together with a forming mold member 12 in a heating furnace so as to be heated up to the predetermined temperature. The fluororesin sheet 13, which is softened to some extent through the above-mentioned heating, is deep-formed into the predetermined shape. The said forming is performed by suckingly discharging the air in the recessed part 11 through a discharge port 15 under vacuum, which is provided at the bottom part 12a of the forming mold member 12. In this case, pressurizing force applied on the fluororesin 13 with the keep ring 14 is set so as to deep-form the fluororesin by being slid between the keep ring 14 and the top surface 10 of the forming mold member 12. As a result, the fluororesin sheet 13 deforms so as to gradually pull its surplus length part 13a in the recessed part 11.
