Abstract

PURPOSE: To decrease the thickness of watch and increase the volume of battery, by composing a battery through combination of watch substrate and case.
CONSTITUTION: A small-diameter recess 9b and a large-diameter recess 9c are formed in a substrate 9 made of conductive material to accommodate anode compound 5, separator 6, gasket 4, and cathode compound 8, which are pressed down by a battery lid 11 through spacer 19 made of nonconductive material and a cathode can 3. At the same time, a minus contact piece 13 is provided on the substrate 9 through nonconductive material 20. Thus, the special space for the anode can may be omitted, and the space of conductive structure and space for housing battery are effectively used. As a result, a larger volume may be preserved for battery, and the thickness of the watch may be reduced and the life time will be elongated.
