To provide a cooking stove comprising a touch switch capable of forbidding the instruction to start the operation of a heating means by a child, and permitting the instruction to stop the heating means by the child.
This cooking stove comprises a capacitance type operation switch 10 for switching the cooking stove between an operation state where the ignition can be instructed and a standby state where the ignition can not be instructed, and instructing the extinction of flame. A resisting element 61 of high resistance is selected by a switch circuit 63 when the cooking stove is in a flame extinction state to achieve "low sensitivity set state" where the sensitivity of the operation switch 10 is s1, thus the switching to the operation state is forbidden when the child touches a touch area 10a in the standby state. when the cooking stove is in a burning state, a resisting element 62 of low resistance is selected by the switch circuit 63 to achieve " high sensitivity set state" where the sensitivity of the operation switch 10 is sh(>s1), thus the execution of flame extinguishing process of a burner is permitted when the child touches the touch area 10a.
