Provided are a laminate excellent in heat resistance, and a separator for capacitors comprising the laminate. The laminate comprises a nanofiber layer and a base layer, the nanofiber layer comprising polyamide filaments formed from a polyamide (a) and having an average fiber diameter of 10 to 1000 nm, and the base layer comprising fibers at least including polyamide fibers formed from a polyamide (a). The polyamide (a) comprises a dicarboxylic acid unit and a diamine unit, wherein (i) the dicarboxylic acid unit comprising terephthalic acid unit in the proportion of not lower than 60% by mole, and (ii) the diamine unit comprising at least one diamine unit selected from the group consisting of 1,9-nonanediamine unit and 2-methyl-1,8-octanediamine unit in the proportion of not lower than 60% by mole in total.
