The present invention discloses a baking device with automatic temperature measurement and heating function, and is connected with a power source, including: a housing, which opens a groove toward the baking object; an infrared temperature sensor is disposed in the groove of the housing and is automatically output. a temperature sensing signal; a control module, disposed in the housing, for receiving the temperature-sensitive signal and determining whether the surface temperature of the baked product meets a predetermined temperature; if not, outputting a control signal; and an infrared heater disposed in the recess of the housing is used to receive the control signal, and infrared heating is performed on the baked object according to the control signal. If yes, by controlling the infrared temperature sensor and the infrared heater to automatically measure and heat the baked goods, the baked goods can be maintained at an appropriate temperature without cooling, thereby improving the storage quality and the convenience of eating.
