PROBLEM TO BE SOLVED: To provide a means to prevent the waviness and creases of a chemical-resistant sheet from occurring and improve the surface smoothness of a sheet base material side in a method for manufacturing a chemical-resistant sheet obtained by joining the sheet base material of polytetrafluoroethylene resin with glass cloth into one piece through a melt fluid fluororesin layer using a continuous technique. SOLUTION: A sheet base material 1, film 2 of a melt fluid fluororesin and glass cloth 3 are laminated in such a manner that the film 3 is sandwiched in between by paying off the described materials 1, 2, 3 continuously from winding rolls R1-R3. Further the laminate is thermally contact-bonded by making it pass through gaps between a high temperature roll H1 whose surface temperature is higher than the melt point of the fluororesin of the film 3 and low temperature rolls C1, C2 which have a lower surface temperature than the melt point and form nip parts 4a, 4b with the high temperature roll H1 respectively.
