PROBLEM TO BE SOLVED: To provide an integrally molded button structure with reduced number of parts, preventing permeation of water or the like from outside, and preventing erroneous switching-on which happens when another part other than a button part of an upper case is pushed. SOLUTION: A button part 3 of the integrally molded button structure, turning on a switch by pushing the button part 3 formed on an upper case 2 of an electronic device 1 having waterproof function preventing the permeation of water or the like by the upper case 2 and a lower case 21, is integrally molded to the upper case 2 of the electronic device 1 without forming any grooves preventing water permeation or the like. The wall thickness of the button part 3 is made to have an elasticity by forming thinner than the upper case 2, and the button part 3 is jointed to the upper case 2 with a smoothly curved surface, and made to curve in convex-shape. A protrusion part 6 is formed on the upper case 2 which holds the button part 3 so as not to be pressed by the influence of the pushing of the upper case 2 even if an another part than the button part 3 on the upper case 2 is pushed.
