A radiant heating device for a vehicle includes a radiant heater that radiates radiant heat toward a passenger and is provided together with an air-conditioner that selectively introduces air outside a passenger compartment or air inside the passenger compartment and then supplies conditioned air generated from the introduced air into the passenger compartment. The radiant heating device includes a controller that differentiates a radiant energy amount of the radiant heater when the introduced air into the air-conditioner is the air outside the passenger compartment from when the introduced air is the air inside the passenger compartment. According to the radiant heating device, the passenger can be provided with warm comfort feeling both in an outside air intake mode and in an inside air intake mode of the air-conditioner.
