ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERIES, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY PROVIDED WITH SAME

An electrode for nonaqueous electrolyte secondary batteries, which is provided with a collector and a positive electrode active material layer that is arranged on the collector and contains a positive electrode active material. The positive electrode active material is configured to contain compound particles which have a layered structure composed of two or more transition metals, and which have an average particle diameter DSEM of from 1 μm to 7 μm (inclusive), a ratio of the 50% particle diameter D in a volume-based cumulative particle size distribution to the average particle diameter DSEM, namely D/DSEM of from 1 to 4 (inclusive), and a ratio of the 90% particle diameter D in the volume-based cumulative particle size distribution to the 10% particle diameter D in the volume-based cumulative particle size distribution, namely D/D of 4 or less. The positive electrode active material layer has a void fraction of 10-45%.
