Abstract

Provided is a laminate for an electrochemical device that can advantageously be used as a device member having excellent low-temperature adhesiveness and blocking resistance. The laminate includes a functional layer containing heat-resistant fine particles and adhesive particles and a substrate. The adhesive particles contain an adhesive polymer that includes an aromatic vinyl monomer unit and a wax that has a melting point of lower than 95° C. In plan view of the laminate from a side corresponding to the functional layer, the functional layer includes an adhesion region formed of the adhesive particles and a heat-resistant region formed of the heat-resistant fine particles. The volume-average particle diameter of the adhesive particles is larger than the average stacking direction height of the heat-resistant region.
