Thermistor layer, electrode for battery, battery, and thermistor

A thermistor layer configured to be disposed in an electrical current path, wherein

• the thermistor layer comprises thermosensitive particles, a plurality of electro-conductive particles covering a surface of each of the thermosensitive particles, and a binder adhering the electro-conductive particles,
• the electro-conductive particles form an electro-conductive network,
• an average particle diameter of the thermosensitive particles is larger than an average thickness of the thermistor layer,
• at least the surface of each of the thermosensitive particles is made of a thermoplastic resin,
• the thermoplastic resin has the property of softening at a temperature lower than a temperature at which the binder softens, and
• the thermistor layer is provided to become highly resistive due to softening and deformation of the thermoplastic resin.
