<p>PROBLEM TO BE SOLVED: To provide a laminate having excellent heat resistance, especially a separator for capacitor formed of this laminate.SOLUTION: A laminate has a nanofiber layer and a base material layer, and the nanofiber layer is formed of polyamide filament having an average fiber diameter of 10-1000 nm composed of polyamide (a). The polyamide (a) is constituted of dicarboxylic acid unit and diamine unit, and (i) 60 mol% or more of dicarboxylic acid unit is telephthalic acid unit, (ii) 60 mol% or more of diamine unit is at least one kind of diamine unit selected from a group consisting of 1,9-nonanediamine unit and 2-methyl-1,8-octane diamine unit, and the base material layer is formed of fibers at least containing polyamide fibers composed of the polyamide (a).</p> |
