Abstract
A porous sheet, which is produced by the process comprising: molding a resin composition into a sheet, the resin composition comprising from 55 to 90 parts by weight of a crystalline polyolefin having a melt index of not higher than 3 g/10 min and from 10 to 45 parts by weight of a compound containing an ester bond in the molecule thereof and having a vaporizing temperature of 240 ℃ or higher under atmospheric pressure and a melting point 100 ℃ or lower; and at least monoaxially stretching the sheet; and orienting the sheet at least unidirectionally; in which the crystalline polyolefin resin is polypropylene resin or a copolymer of propylene and ethylene; the compound is an ester formed from an alkyl alcohol and one or more polybasic carboxylate selected from phthalate, trimellitic acid, pyromellitic acid, and aliphatic polybasic carboxylic acid, or from an ester of a monocarboxylic acid and a polyol.
