An opening part 4 opened toward a plurality of the terminals is formed at a first wall part 3a of the case 2. An annular seal face 5 is formed at a periphery of the opening part 4. The case 2 is manufactured by die-casting. At the manufacturing, a gate is connected to a region S2 which forms a second wall part 3b opposing the first wall part 3a out of a cavity space S in a metal mold. A connecting part 6 which straddles the inside of the opening part 4, and is connected to an internal peripheral face 40 of the opening part 4 is formed at the case 2. |
