The conductive microparticle layer (2) is formed with first pores (3) of no less than 0.5µm and no more than 50µm and second pores (4) of no less than 0.05µm and less than 0.5µm. Pores (11) are also formed in the base material layer (1). A total volume of the second pores (4) is no less than 50% and less than 100% of a total volume of all of the pores in the conductive microparticle layer (2). By setting a pore size D1 of pores having a maximum volume ratio from among the first pores 3 such that a capillary force F1 acting on the first pores 3 is smaller than a capillary force F2 acting on the pores (11) in the base material layer (1), water passages are formed in the first pores (3) separately from gas passages formed in the second pores (4).",
