Electrode for secondary batteries, and secondary battery

Abstract

Provided is an electrode for secondary batteries, which is capable of suppressing deterioration of rapid charge and discharge characteristics. An electrode for secondary batteries constitutes a winding-type electrode body provided with a band-like core body and a mixture layer disposed on the core body, and is characterized in that: a longitudinal-direction-side first exposed portion, in which the mixture layer is not disposed, is provided at one end part in the longitudinal direction of the core body; the longitudinal-direction-side first exposed portion is covered with a first insulating portion; and a short-direction-side first exposed portion, in which the mixture layer is not disposed, is provided at a position separated from both end parts in the longitudinal direction of the core body at one end part in the short direction of the core body.
