PROBLEM TO BE SOLVED: To provide a battery case easy to manufacture and without fear of electrolyte solution leaking out after a long-time use and a battery easy to be mounted. SOLUTION: The battery case B is provided with a base body 1 made of ceramics having a rectangular parallelepiped concave part 1a at the center part of its top face, a stepped part 1c formed over a whole periphery between its inner side faces and bottom face, and a first conductive layer D and second conductive layer C on an underside, a metallized layer 1b formed at a bottom face of the concave part 1a, a first connecting conductor 3a formed from a periphery of the concave part 1a at the top face of the base body 1 over to the first conductive layer D, a second connecting conductor 3b formed from the metallized layer 1b over to the second conductive layer C, and a lid body 2 fitted into a top face of the stepped part 1c and fitted through a resin jointing agent with at least an underside main face and side faces made conductive with the side faces and the first connecting conductor 3a electrically connected with each other through conductive resin.
