PROBLEM TO BE SOLVED: To provide an operation button device for a game machine capable of obtaining an excellent operation touch or the like even when continuously performing operations along the array of operation buttons. SOLUTION: In the operation button device for the game machine, a plurality of operation parts 5a for operating pressurizing switches 2a are arrayed at intervals on a panel surface 4, and slopes 42a of a rising gradient to the peak parts of the respective operation parts 5a along the array direction of the operation parts 5a are formed adjacently to the respective operation parts 5a on the panel surface 4. A slope 46a formed between the operation part 5a and the operation part 5a includes a finger receiving slope 43a and a finger feeding slope 42b. The finger receiving slope 43a is formed by being sloped to rise to the rear end from the almost same height as the peak part of the operation part 5a positioned at the front while being pressurized. The finger feeding slope 42b is continued with the finger receiving slope 43a and is formed by being sloped to rise to the almost same height as the peak part of the operation part positioned at the back while not being pressurized.
