Abstract The present invention relates to an overheat protection device for a scroll compressor which can prevent a sealing member from being damaged due to the overheat, by detecting a temperature of an inhaled or discharged gas of the compressor and directly stopping driving of the compressor, without using a special controller, when the gas temperature exceeds an adequate temperature. In the scroll compressor having in a casing an orbiting scroll and a fixed scroll for inhaling, compressing and discharging a gas, and a driving motor for driving the orbiting scroll, an overheat protection device for the scroll compressor stopping the driving motor when a detected temperature exceeds an adequate temperature, a temperature detection device for detecting a temperature of the gas of a low pressure region where the gas is inhaled and a high pressure region where the gas is discharged through a discharge port of the fixed scroll being connected between a power terminal and the driving motor in an electrical serial state.
