置。[Scope of Claim for Utility Model Registration] Charging means for charging a capacitor; and first discharging time measuring means for discharging the electric charge of the capacitor charged by the charging means into a circuit including a resistive temperature sensor and measuring the discharging time. and second discharge time measuring means for discharging the electric charge of the capacitor charged by the charging means into a circuit not including a resistive temperature sensor and measuring the discharge time; and a temperature calculation means for calculating a temperature based on the discharge times respectively measured by the first discharge time measurement means and the second discharge time measurement means, If the change in the discharge time measured by the first discharge time measuring means with respect to the discharge time held by the holding means is within a predetermined value, the discharge time previously measured by the second discharge time measuring means is changed. The temperature is calculated by the temperature calculating means using the current discharge time measured by the first discharge time measuring means, and the first discharge time is calculated with respect to the discharge time held by the holding means. If the change in the discharge time measured by the measuring means exceeds a predetermined value, the contents of the holding means are updated to the current discharge time measured by the first discharge time measuring means, and the second discharge time measurement is performed. A temperature measurement device characterized in that the temperature calculation means calculates the temperature by measuring the discharge time by the means and using the current discharge time measured by the first discharge time measurement means.
