BATTERY PLATED WITH NICKEL BRIGHT PLATING

摘要

PPROBLEM TO BE SOLVED: To provide a battery in which a superior contact state that can take out large current efficiently from the battery of high capacity at a low voltage can be secured stably over a long time without increasing the cost, without forcing special burden upon an equipment side, or without largely losing superior appearance. PSOLUTION: In the battery having electrode terminal parts 12a, 32a in which a steel sheet has been plated by nickel bright plating, a finishing section of the steel sheet surface is dull-finished, and ratio of sulfur and a sulfur compound in nickel bright plating is made to be 0.02 wt% or less.
