Abstract
A first electrode and a second electrode to be used are electrodes each of which has a collector, and a porous material layer with electron conductivity placed between the collector and a separator, and each of which has a configuration wherein the porous material layer includes 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 Tlower than a softening point Tof the separator. A production method includes a thermal treatment step of thermally treating a laminate at a thermal treatment temperature Tsatisfying a condition represented by Formula (1): T≦T<T, thereby bringing the collector of the first electrode, the porous material layer of the first electrode, the separator, the porous material layer of the second electrode, and the collector of the second electrode in the laminate into an integrated state.
