PROBLEM TO BE SOLVED: To provide a technique for suppressing degradation of durability and an output/input characteristic in a high temperature area within a normal use temperature zone by increasing the increase start temperature of inner resistance in a positive electrode plate for a nonaqueous electrolyte power storage element which increases the internal resistance when the temperature exceeds the normal use temperature zone.SOLUTION: In a positive electrode plate for a nonaqueous electrolyte power storage element, an intermediate layer containing conductive agent and fluorine-contained resin binder is provided between a positive electrode collector and a positive electrode mixture layer, and the porosity of the positive electrode mixture layer is set to 39% or less, whereby the increase start temperature of the inner resistance can be increased, and degradation in durability and output/input characteristic in a high temperature range within a normal use temperature zone can be suppressed.SELECTED DRAWING: Figure 1 |
