Abstract:
1. A method of producing an electrochemical device which comprises a laminate having a first electrode and a second electrode facing each other, and a porous separator adjacently placed between the first electrode and the second electrode, and in which the first electrode and the second electrode are electrodes each having a collector, and a porous material layer with electron conductivity placed between the collector and the separator, the method comprising making the porous material layer, using as constituent materials, at least particles of a porous material with electron conductivity, and a thermoplastic resin being capable of binding the particles of the porous material together and having a softening point T the method comprising a thermal treatment step of thermally treating the laminate at a thermal treatment temperature T
