NOVELTY - The battery (10) has a wound electrode assembly (14) formed by winding a positive electrode sheet and a negative electrode sheet with a separator. The assembly is placed in an outer body (25), so that a winding axis direction of the assembly is parallel to a bottom face of the outer body. A high-melting-point material (30) includes melting point higher than the melting point of a material constituting the outer body placed between one of ends of the assembly in the winding axis direction and a lateral face of the outer body facing the end of the assembly in the direction.    USE - Prismatic non-aqueous electrolyte secondary battery for use in a vehicle e.g. electric vehicle (EV), hybrid EV (HEV) and plug-in HEV (PHEV).    ADVANTAGE - The high-melting-point material is electrically connected to the positive electrode, electropositive potential of the positive electrode causes, or decomposed using an electrolyte component, thus reducing safety and reliability of the battery. The high-melting-point material is electrically connected to the negative electrode, and a material that readily forms an alloy with lithium forms the alloy with lithium to reduce battery reliability or cycling characteristics. The battery includes a negative electrode collector connected to the negative electrode terminal followed by resistance welding of the negative electrode collector to a negative electrode substrate exposed portion, thus leading to easy positioning during resistance welding to improve production efficiency. The battery includes a protrusion with no opening works in similar manner to related-art projection method during resistance welding, such that current is concentrated around the opening during resistance welding to improve a heat generating condition, thus achieving better resistance welding. The battery includes conductive intermediate units held by and fixed to the intermediate unit made of a resin material, thus improving dimensional precision between the set of conductive intermediate units and enabling stable positioning of the intermediate units between the bisectional substrate exposed portions, and hence improving quality and achieving low resistivity, improving output power and reducing variation in the output power.
