PROBLEM TO BE SOLVED: To provide a safe gas cooking stove for detecting blocking-up of a combustion gas passage. SOLUTION: A table cooking stove 1 controls combustion gas supply to a cooking stove burner 20 on the basis of a result when detecting the blocking-up of the combustion gas passage 34 on the basis of detecting pressure of a pressure sensor 40 arranged in an air supply passage 7. In this case, supply of combustion gas may be stopped, and a supply quantity may be reduced. Or a gas supply quantity may be controlled in response to its blocking-up degree. As a result, combustion failure is prevented, and safety is improved. The narrow combustion gas passage 34 is formed for increasing high heat efficiency, for being particularly suitable for the table cooking stove 1 having a constitution of easily causing clogging of soup.
