    摘要： A battery includes a current breaking mechanism 20 provided in a battery and configured such that an external terminal 21 connecting a terminal rivet 31 connected to a power generating element 16 to an electrode terminal is provided with thick portions 48 and 49 and a breakable portion 45 so that the thick portions 48 and 49 are continuous through the breakable portion 45 only. The battery further includes: the terminal rivet 31 placed passing through a closing plate 12 forming a part of a battery case 11, a part of the terminal rivet 31 located outside the battery case 11 being placed on the thick portion 48 of the external terminal 21 in close contact relation, the terminal rivet 31 having a through hole 32; and a sealing cap 25 covering an exit of the through hole 32 on the outside of the battery case 11 and being joined to the external terminal 21 over the entire circumference of the through hole 32 or joined to both the external terminal 21 and the terminal rivet 31 across them. When the internal pressure of the battery case 11 rises, at least part of the sealing cap 25 is moved away from the battery case 11, deforming a part of the external terminal 21, thereby breaking the breakable portion 45.
