Abstract

A circuit substrate mounting configuration for mounting an IC chip having a built in semiconductor sensor in an electronic timepiece is provided. The circuit substrate is fixed to a base plate at at least two points spaced as far as possible from the IC chip so that the substrate about the IC chip does not contact other elements of the timepiece.
