PROBLEM TO BE SOLVED: To provide a push button structure to which a counter measure for preventing intrusion of spilled soup is taken to small push buttons mounted on an attached unit like an operation part for temperature control, a timer or the like. SOLUTION: A button 24 having frame bodies is formed by making frame bodies 24a, 24b, 24c, 24d support a push button side face part 27. An inside space 35 surrounded by a sheet film 33, an operation panel 17, and the frame bodies 24a, 24b, 24c, 24d, is formed by airtightly fitting the frame bodies 24a, 24b, 24c, 24d between peripheral parts 32a, 32b of an opening on which, the film sheet 33 is adhered and the operation panel 17, in a state of arranging a push button 21 of the button 24 having frame bodies, a button hole 29, and a switch hole 30 in a line in push-in direction. Furthermore, the push button 21 is pushed in and pulled out while keeping a close contact between the push button 21 and the button hole 29, and the inside space 35 is made airtight by adhering double-side adhesive tapes 38a, 38b on panel back faces 37a, 37b at whole peripheral position of the outside peripheral edge of adhesion faces 36a, 36b between the operation panel 17 and the frame bodies 24a, 24b, 24c, 24d.
