NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery reducing the manufacturing failure rate of the battery and having an excellent high-rate discharge characteristic. SOLUTION: This nonaqueous electrolyte secondary battery is provided with a power generating element formed by piling, winding or laminating a positive electrode plate, a separator, a negative electrode plate and a separator in this order, and only the edge part of at least one electrode plate out of the positive and negative electrode plates is projected from one end face of the power generating element. In this case, through holes or/and cutout parts are formed in a mixture unapplied part provided at a base material at the projected edge part of the electrode plate.
