A cooking stove which prevents the quantity of heat generated by a gas burner from increasing continuously contrary to the user's expectations, while allowing the user to easily operate the appliance. A cooking stove includes an operation portion 6 having touch switches provided on a glass top plate 2 covering a top surface of a cooking stove main body 1 accommodating burners 4 a and 4 b, the touch switches allowing a user to give instruction on activation of the burners 4 a and 4 b, the touch switches sensing an object that contacts or approaches the top surface of the glass top plate 2 , and a controller for determining whether each of the touch switches is on (sensing state) or off (non-sensing state) to control activation of the burners 4 a and 4 b in accordance with the result of the determination. When a thermal power up switch for the burner 4 a in the operation portion 6 is kept on while the burner 4 a is in operation, controller increases the thermal power of the burner 4 a by only one level. When a thermal power down switch for the burner 4 a in the operation portion 6 is kept on while the burner 4 a is in operation, the controller continuously reduces the thermal power of the burner 4 a by a plurality of levels.
