PROBLEM TO BE SOLVED: To ensure confirmation of combustion through visual observation of flames. SOLUTION: Burner heads 11 of cooker burners 2, 3 are, respectively, radially inserted with four ceramic rods 13, 13... at the circumferential edges thereof. With the ignition of the burners 2, 3, the tips of the ceramic rods 13, 13... are heated and turn to red. The red color is mixed with the blue color of flames, which is generated by combustion of gas so as to emit bright light. Thus, the flames can be immediately visually observed by aged persons who suffer from cataract, or the like persons, making it easy to confirm combustion.
