PROBLEM TO BE SOLVED: To provide a sealed battery comprising a lid which reduces an extent of deformation.SOLUTION: In an insulation member 80, a portion (insulation power receiving part 83) which is pressed by an external terminal 37 and brought into contact with a surface (top face 13p) of a lid 13 by receiving a caulking force from a caulk member (positive electrode connection member 35) via the external terminal 37 is formed in a curved shape while protruding in a load direction Z of a caulking load F when the portion is watched in a length direction X of the lid 13 in the state where the caulking force is not received, and formed in a curved shape while protruding in the load direction Z of the caulking load F or in an opposite direction when the portion is watched in a width direction Y of the lid 13. The portion is elastically deformed while being fastened by receiving the caulking force, and a face (bottom face 83c) turned towards a side of the lid 13 is brought into tight contact with the surface (top face 13p) of the lid 13.SELECTED DRAWING: Figure 7 |
