Abstract: A substrate for a liquid filter contains a polyolefin microporous membrane. A mean flow pore size dPP in a pore size distribution of the polyolefin microporous membrane measured by a half dry method according to gas-liquid phase substitution is from 1 nm to 20 nm. A mean flow pore size dLLP in a pore size distribution of the polyolefin microporous membrane measured by a half dry method according to liquid-liquid phase substitution is from 1 nm to 15 nm. A difference (dPP−dLLP) between the mean flow pore size dPP and the mean flow pore size dLLP is 12 nm or less, and a thickness of the polyolefin microporous membrane is from 4 to 25 μm.

Abstract: Provided are a method of producing a metal member, a method of producing a resin member, and a method of producing an exterior part of a vehicle, each using a laminated body including a paint substitute film that includes a thermoplastic resin film, a colored layer, and a semi-cured hard coat layer, in this order, and a protective film that is bonded to a surface of the semi-cured hard coat layer. (1) The method of producing a metal member uses a steel plate together with the laminated body, and includes: a molding step of performing thermocompression bonding on the laminated body and the heated steel plate and performing press-molding while curing the semi-cured hard coat layer. (2) The method of producing a resin member uses a molten resin together with the laminated body, and includes: inserting the laminated body into a mold; performing in-mold molding by performing injection-molding using the molten resin; and curing the semi-cured hard coat layer after the insertion into the mold and until the in-mold molding ends. (3) The method of producing an exterior part of a vehicle includes combining the metal member produced by the above-described method, and the resin member produced by the above-described method.
