Abstract: Provided is an electric storage device that can ensure seal in a peripheral area of a portion in a defining wall of a case through which a rivet passes even when a rivet is inserted through the defining wall of the case and the rivet is caulked. The electric storage device includes: an electrode assembly; a case that houses the electrode assembly, the case including a defining wall; and a rivet, wherein a peripheral area of a portion in the defining wall through which the rivet passes has a higher hardness than the remaining area.

Abstract: A conductor for connecting terminals of a battery in which a conductor for connecting terminals (8) can be easily welded to both positive-electrode terminal (1) and negative-electrode terminal (4), and an assembled battery using the same are provided. The conductor for connecting terminals (8) is formed in such a manner that a plate-shaped part (8a) including an aluminum member is overlapped with a plate-shaped part including a second metal having a melting point higher than that of the aluminum member, a first region having the exposed aluminum member and a second region having the exposed second metal are formed in one surface, and the second metal is exposed to a region opposed to the second region, in the other surface. The conductor for connecting terminals (8) connects the positive-electrode terminal (1) including the aluminum member of a non-aqueous electrolyte secondary battery (7) to the negative-electrode terminal (4) of another battery.

Abstract: A health condition determining device accumulates data measured or input by an evaluation subject for each index of a plurality of items including a lifestyle index, which is an index related to body activity or lifestyle habit, and a biomarker, which is an index related to physiological state of the body. The health condition determining device then selects one or a plurality of biomarkers that lowers the evaluation of the health condition of the evaluation subject as a problematic index, extracts one or a plurality of lifestyle indices having the highest correlation with the problematic index as an improvable factor by comparing accumulated past data of the lifestyle index and the biomarker, and displays the improvable factor along with the evaluation of the health condition of the evaluation subject.

Abstract: It is an object of the present invention to provide a battery in which current collecting connector 2 and 3 and groups 1d and 1e of metal foil of a power generating element 1 can be easily connected, respectively, and a method of manufacturing the same. First plate portions 2b and 3b which respective protruding ends of metal foil of the groups 1d and 1e of metal foil of the power generating element 1 come in contact with or close to and second plate portions 2c and 3c protruding from the first plate portions 2b and 3b toward the power generating element 1 and disposed only at one outer side portions of the groups 1d and 1e of metal foil are provided to the other portions of the current collecting connectors 2 and 3 of the invention and the groups 1d and 1e of metal foil are welded to the second plate portions 2c and 3c.
