The present invention relates to an indoor temperature sensor of a vehicle, which is able to detect a temperature of the internal side of the vehicle by using an infrared light sensor and an optical sensor, to reduce noise, and to decrease costs by a precise temperature measurement and a simple structure. According to the present invention, the indoor temperature sensor of the vehicle comprises: a PCB (110); an infrared light sensor (120) mounted on a front end unit (111) on one side of the PCB (110) to detect a surface temperature of a sensing unit (142) of a sensing cover (140); an optical sensor (130) for detecting a solar radiation quantity mounted on a front end unit (111) on one side of the PCB (110) to detect a solar radiation quantity incident into the sensing unit (142) of the sensing cover (140); and the sensing cover (140) having a hollow unit (141), which is mounted on a side of the front end unit (111) of the PCB (110) to allow the infrared light sensor (120) and the optical sensor (130) to be placed on the sensing unit (142) inside the hollow unit (141). According to the present invention, the indoor temperature sensor of the vehicle is able to determine an indoor temperature of the vehicle by a temperature value detected by the infrared light sensor (140) and to correct the indoor temperature measurement by using the solar radiation quantity detected by the optical sensor (130).
