To shorten a time period of a catalyst heating without increasing the cost largely. A catalyst heating system 1 for heating a catalyst provided at an exhaust passage 5 of a vehicle, the system comprises a purifying catalyst 6 provided in the exhaust passage 5, a water storage part 2 provided at an upstream of the purifying catalyst 6 in the exhaust passage 5 and along a bottom side of the exhaust passage 5, an upper part of the water storage part 2 being opened to the exhaust passage 5, an electromagnetic wave emitter 3 arranged above the water storage part 2 and configured to emit an electromagnetic wave to moisture stored inside the water storage part 2, thereby heating up the moisture and generating water vapor therefrom, and a controller 4 configured to control the electromagnetic wave emitter 3, and the controller 4 controls the electromagnetic wave emitter 3 to emit the electromagnetic wave for a predetermined time period when an engine of the vehicle starts to run.
