PROBLEM TO BE SOLVED: To provide an operating button unit having increased electrostatic resistance with large surface distance, keeping sufficient surface distance even if electric parts are placed near the operating button, and enabling to protect the elastic deformated part in the operating button from hardening and plastic deformation. SOLUTION: The unit is an operating button unit equipped with an operating button 3 which applies operating force to a parts to be operated 5. The operating button 3 comprises a first parts 31 to which an operator applies an operating force with direct touch and a second parts 32 which incorporates an elastic deformation parts 32c and applies operating force to the parts 5 with angular displacement. Surface treatment including metal 31f is made on the surface of the first parts 31.
