PROBLEM TO BE SOLVED: To separate an electronic part and a mechanism part in an electronic force balance to prevent the thermal influence on the electronic part so that the electronic part can perform a large-capacity, high-speed operation without considering the thermal influence. SOLUTION: The mechanism consisting of a weighing tray 3, a load transmitting mechanism 4, a Roberval mechanism 5, an electromagnetic part 7, a position sensor 7 and the like is made into an independent device as mechanism part 1. The electronic part 2 for controlling the mechanism part 1 and variously processing measurement data is also made into a device perfectly independent from the mechanism part 1, and the both are mutually connected through an information transmitting means such as cable, whereby one electronic force balance is constituted as the whole.
