The present invention provides a method for producing a porous resin sheet for piezoelectric / pyroelectric elements having excellent piezoelectric performance, and a porous resin sheet for piezoelectric / pyroelectric elements produced by the method. A method of manufacturing a porous resin sheet for piezoelectric / pyroelectric elements includes a laminated sheet 3 provided with an insulating plate 2 on at least one surface of a porous resin sheet 1 with electrodes, between electrodes 4 and 5 for voltage application. And a step of charging the inside of the bubble of the electrode-coated porous resin sheet 1 by applying a voltage between the voltage application electrodes 4 and 5. [Selection] Figure 2 |
