Abstract:
Provided is an oxygen permeable membrane for use in an air secondary battery, which excels in oxygen permeability, barrier performance to water, being capable of preventing electrolyte from leaking out. Such an oxygen permeable membrane includes a thermoplastic resin membrane and inorganic particles having pores having pore diameter of 10 Å or less contained in the thermoplastic resin membrane, in which the thermoplastic resin membrane has one surface on which hydrophobic treatment is effected.
