PURPOSE: To reduce the number of parts in an electronic watch structure containing a thin, wide-area battery, by using the base holding fixture also as a battery container.

CONSTITUTION: The metal fixture 4 is fixed by hooking the hole 11 of the fixed part 12 to the projection 6 of the module frame 1. This also allow the fixture 4 to fix the circuit base 2 and the insulating sheet 3. The fixture 4 having the positioning piece 13 to hold the battery 5 functions to position the battery 5 and as the outer electrode terminal for the battery 5. The fixture 5 is connected by the contact piece 14 to the electrode 9 of the base 2. Inner electrode of the battery 5 contacts the terminal plate 10 at the center of the insulating sheet 3 and is connected to the electrode 8 of the base 2.
