PROBLEM TO BE SOLVED: To easily connect to an external electric circuit board without leakage of an electrolytic solution due to the generation of a gap in a battery and without imparting a damage to the board. SOLUTION: A battery case B is equipped with a ceramic base material 1 wherein a recess part 1a of a rectangular parallelepiped shape is formed at the center part of the upper face and a step 1c is formed between the inner side face and the bottom face of the recess part 1a, a first metallized layer 1d formed on the upper face of the step 1c, a second metallized layer 1b formed on the bottom face of the concave 1a, a first groove D and a second groove C disposed on the outer side face of the base material 1 wherein a first conductor layer D-1 and a second conductor layer C-1 are formed in the inner faces, respectively, and an internal conductor 3 formed from the first layer 1d to the first layer D-1 and from the second layer 1b to the second layer C-1, respectively.
