PROBLEM TO BE SOLVED: To provide a case for a battery capable of preventing an electrolyte from leaking out due to a gap generated in the battery, and easily connected to an external electric circuit board without damaging the external electric circuit board. SOLUTION: This case B for a battery is provided with: a ceramic substrate 1 composed by forming a rectangular parallelopiped recessed part 1a at a center part of its upper surface, and by forming a step 1c between the inside surface and the bottom surface of the recessed part 1a; a first metalized layer 1d formed on the upper surface of the step 1c; a second metalized layer 1b formed on the bottom surface of the recessed part 1a; a first conductor layer D and a second conductor layer C formed on the outside surface of the ceramic substrate 1; and internal conductors 2 respectively formed from the metalized layer 1d through the conductor layer C, and from the metalized layer 1b through the conductor layer C. A metallic frame-like member 3 is brazed to the upper surface of the substrate 1 so as to surround the recessed part 1a. COPYRIGHT: (C)2005,JPO&NCIPI |
