PROBLEM TO BE SOLVED: To provide a clock which can be manufactured with a high yield. SOLUTION: A plus electrode plate 15 connected with the plus electrode of a cell 2 is supported by a protrusion 5b of an under plate 5. A protrusion 4a of a dust cover 4 presses a part 15a of plus electrode plate 15 toward the under plate 5 and a part 15c of plus electrode plate 15 is pressed against the plus electrode connection pattern 1a of a circuit board 1 by the lever action around the protrusion 5b as fulcrum. The surface of circuit board 1 is pressed by the protrusion 4b of dust cover 4 toward the under plate 5. |
