PROBLEM TO BE SOLVED: To provide a gas cooking stove capable of effectively controlling the heating amount to a cooked material placed on a to plate of an upper face of a combustion chamber by ON/OFF control of a burner. SOLUTION: A temperature range determining means 32 determines an upper limit temperature and a low limit temperature to control a temperature of a glass top plate 4 in accordance with the heating amount determined by a heating amount determining switch 8. A heating control means 33 starts the combustion in the burner 2 when a temperature of the glass top plate 4 grasped by a top plate temperature grasping part 31 on the basis of a temperature detected by an exhaust gas temperature sensor 10, becomes lower than the lower limit temperature. Further the heating control means 33 stops the combustion in the burner 2, and operates an air supplying and exhausting fan 6 with a rotating frequency lower than that in a post-purging processing in stopping the heating operation, to perform the post-purging processing, when the temperature of the glass top plate 4 becomes higher than the upper limit temperature.
