PURPOSE: A circuit for measuring a load of a load cell is provided to solder an inductor in a smaller size than a copper wire, thereby forming an excellent exterior. CONSTITUTION: A circuit for measuring a load of a load cell comprises strain gauges(SG1,SG2,SG3,SG4), inductors(L), a core(C), and a wire(W). A power source(Vin) where anode and cathode are connected to connecting points between the strain gauges is connected in parallel so that the Wheatstone bridge can be formed. While a current for measuring a load which is applied from the outside flows in the Wheatstone bridge by being supplied from the power source, an output voltage is output through an output terminal. The inductors are arranged in at least one side of both sides of the strain gauge which is arranged between the connecting points. The inductor has rating resistance corresponding to a direct-current resistance component.
