Abstract
An inorganic particle layer for use in an electrode of a non-aqueous electrolyte power storage element is provided. The inorganic particle layer includes an inorganic particle and a polymer. The inorganic particle is insulating and has a surface potential. The polymer has an ionic functional group (A) and an ion-conducting functional group (B) each charged opposite to the surface potential of the inorganic particle. The inorganic particle and the polymer are bonded to each other.
