Abstract: According to the present invention, a non-aqueous electrolyte secondary battery includes an accommodation container including a positive electrode can, a gasket, and a negative electrode can, and a power generation element containing an electrolytic solution. The positive electrode can is formed in a bottomed-cylindrical shape having a bottom wall portion and an outer wall portion. The negative electrode can is formed in a topped-cylindrical shape having a top wall portion and an inner wall portion. A portion of the outer wall portion located on a top wall portion side is made as a crimping portion 12b curved with a curvature radius R gradually toward an inner wall portion side as it extends from a bottom wall portion side toward an opening end edge of the outer wall portion. A diameter D of the non-aqueous electrolyte secondary battery is set to 4.6 mm to 5.0 mm. A height H2 of the positive electrode can is set to be in a range of 74% to 79% of a height H1 of the non-aqueous electrolyte secondary battery. The curvature radius R of the crimping portion is set to be in a range of 0.7 mm to 1.1 mm.

Abstract: An electrochemical cell includes at least a base container, a cell which is accommodated in the base container, a plurality of cell leads which are extension portions of the cell, a pad film which is formed of valve metal on a base bottom surface, and a base-embedded wiring (a via wiring) which is connected to the pad film and is formed in a portion between the base bottom surface and a base lower surface, in which at least one of the cell leads and the pad film are fixed to each other through ultrasonic welding, and when a horizontal distance between a welding portion and the base-embedded wiring in the pad film is set to be L, and tolerance relating to an installation position of the base-embedded wiring is set to be a, L≧a×1.3 is established.
