Abstract
A sealed battery including: an electrode assembly 11 having multiple positive electrode substrates exposed at one end and negative electrode substrates exposed at the other end; and collectors 181 and collector receiving parts 183 that are resistance-welded on both sides of the multiple positive or the multiple negative electrode substrates or both, grooves 23 being formed around the resistance-welded portion of at least one of the collector 181 and the collector receiving part 183. Due to the spattered particles 26 generated during the resistance-welding being captured within the grooves 23, few particles burst into the inside of the electrode assembly 11 or into the outside.
