PROBLEM TO BE SOLVED: To stably manufacture a porous sheet with good gas permeability and uniform characteristics. SOLUTION: An apparatus provided with a roll 17 for feeding the first thermoplastic resin film 16 so as to bring the film into tight contact with an endless belt 14, a feeder 19 for feeding a thermoplastic resin powder 18 on the first film 16, a roll 22 for feeding the second film 21 on the surface of the powder 18 on the first film 16 and a heater 24 for heating the powder 18, is used. In addition, after the thermoplastic powder 18 is fed on the first film 16 from the feeder 19, the second film 21 is fed on the surface of this laminar powder 18 and under a condition where powder 18 is placed between the first and the second films 16 and 21, the powder 18 is sintered into a sheet 11. |
