Disclosed is a fuel gauge circuit which is disposed on a substrate (20) along with a protection circuit (40) which protects the charge/discharge of a battery (1), characterized by being comprised of a voltage monitoring terminal (T1), a voltage through terminal (T6), and a wire (32). The voltage monitoring terminal (T1) is provided on the side of the substrate, which is opposed to a positive supply terminal (21), and is connected to the positive supply terminal (21) of the substrate and a voltage sensor (31) provided within the circuit. The voltage through terminal (T6) is provided on the side of the substrate, which is opposed to the protection circuit provided on the side opposite to the side of the substrate, which is opposed to the positive supply terminal (21), and is connected to a voltage monitoring terminal (T11) of the protection circuit. The wire (32) connects the voltage monitoring terminal (T1) of the fuel gauge circuit to the voltage through terminal (T11) within the circuit. Cette invention concerne un circuit de jauge à carburant disposé sur un support (20) avec un circuit de protection (40) protégeant la charge/décharge d'une batterie (1), caractérisé en ce qu'il comprend une borne de surveillance de la tension (T1), une borne de passage de la tension ( T2), et un fil (32). La borne de surveillance de la tension (T1), qui est disposée sur le côté du support opposé à la borne d'alimentation positive (21), est connectée à cette borne (21) et à un capteur de tension (31) situé dans le circuit. La borne de passage de la tension (T6) se trouve sur le côté du substrat opposé au côté de ce même support portant la borne d'alimentation positive (21) et est connectée à une borne de surveillance de la tension (T11) du circuit de protection. Le fil (32) relie la borne de surveillance de la tension (T1) du circuit de jauge de carburant à la borne de passage de la tension (T11) à l'intérieur du circuit.
