A composite polymer electrolyte membrane has a high proton conductivity even under low-humidity, low-temperature conditions, a reduced dimensional change rate, a high mechanical strength and high chemical stability, and produces a solid polymer electrolyte fuel cell with a high output and high physical durability, a membrane electrode assembly, and a solid polymer electrolyte fuel cell containing the same. This composite polymer electrolyte membrane contains a composite layer composed mainly of a polyazole-containing nanofiber nonwoven fabric (A) and an ionic group-containing polymer electrolyte (B), the polyazole-containing nanofiber nonwoven fabric (A) being basic.

Provided is an air-permeable sheet () to be used in a state of being interposed between a suction stage () and an air-impermeable substrate () when printing is performed by a sheet-fed method on the surface of the substrate () fixed by suction to the suction stage (), the air-permeable sheet capable of printing a desired printing pattern on the surface of the substrate with high accuracy. The air-permeable sheet () includes a non-woven fabric layer () and a support layer () constituted by a woven fabric or knitted fabric.
