ABSTRACT:
The present invention's manufacturing method for a sealed battery includes: a process whereby a sealed battery application electrode assembly11is formed that has multiple positive electrode substrate exposed portions14at one end and multiple negative electrode substrate exposed portions15at the other end; a process whereby the negative electrode collector181and negative electrode collector receiving part183are brought against both surfaces of the part to be welded on at least the negative electrode substrate exposed portions15, with tape23aconstituted of thermodeposited resin and having an opening231in the center being interposed; and a process whereby resistance welding is effected by passing current between the negative electrode collector181and negative electrode collector receiving part183positioned at the two sides.
