<P>PROBLEM TO BE SOLVED: To provide a storage element capable of suppressing the decline of a function of a pressure regulator over a long period of time. <P>SOLUTION: A storage element 1 includes: a storage element body 2 impregnated with an electrolytic solution; a sheath 3 for hermetically sealing the storage element body 2; and a pressure regulator 4 provided on the sheath 3. The pressure regulator 4 includes a plurality of gas release mechanism portions 10, 11. Further, the pressure regulator 4 allows release of gases from an inside space 8 of the sheath 3 in which the storage element body 2 exists to an outside space 9 by causing the gases from the inside space 8 to pass through the respective gas release mechanism portions 10, 11 in succession, and blocks entry of gases from the outside space 9 to the inside space 8 by the respective gas release mechanism portions 10, 11. A buffer space 12 individually partitioned by the gas release mechanism portions 10, 11 is formed between the respective gas release mechanism portions 10, 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
