When the gas cooking stove is used, the gas cooking stove can stably be installed. When the gas cooking stove is not used, the overall size can be reduced to save the space. Thus, the operability, safety and the portability can be improved. A valve mechanism, an operation member for opening/closing the valve mechanism and a piezoelectric spark unit are provided. Moreover, a stove body is provided which has an upper portion to which a dish is joined and a lower portion provided with a gas-cylinder joining portion to which a gas cylinder is joined. A grate is rotatively supported by the dish. The gas cylinder having a valve-joining cylindrical portion which is integrally formed with the gas cylinder, which accommodates a valve mechanism, in which the valve mechanism is secured and from which a stem is allowed to project over the valve-joining cylindrical portion is joined to the gas-cylinder joining portion in the one-touch manner. The gas cylinder has the valve-joining cylindrical portion which is held by a cylinder holding member.
