CASE FOR BATTERY, AND BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a case for a battery capable of preventing an electrolyte from leaking out even when a gap is generated in the battery and having excellent mass productivity by facilitating connection to an external electric circuit board; and to provide a battery. SOLUTION: This case B for a battery is provided with: a ceramic substrate 1 wherein a rectangular solid-like recessed part 1a is formed at a center part of its upper surface, a step 1c-A is formed between the inside surface and the bottom surface of the recessed part 1a, and a first conductor layer D and a second conductor layer C are formed independently of each other on its lower surface; a first metalized layer 1c-B formed on the upper surface of the step 1c-A; a second metalized layer 1b formed on the bottom surface of the recessed part 1a; and internal conductors 3 respectively formed from the metalized layer 1c-B through the conductor layer D and from the metalized layer 1b through the conductor layer C.
