PROBLEM TO BE SOLVED: To provide a panel member capable of obtaining an excellent operation touch or the like when continuously performing operations along the array of operation buttons. SOLUTION: The panel member 4 is attached to an operation button device for the game machine, and slopes 42a of a rising gradient to the peak parts of respective operation parts 5a along the array direction of the operation parts 5a are formed adjacently to the respective operation parts 5a. A slope 46a 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 to rise to the finger feeding slope 42b from almost the same height as the peak part of the pressurized operation part 5a at the front. The finger feeding slope 42b is continued with the finger receiving slope 43a and is formed to rise to almost the same height as the peak part of the non-pressurized operation part at the back. The cross section in a direction roughly orthogonal to the array direction of the slidable contact surface 44a of the finger receiving slope 43a is curved, and the cross section in the direction roughly orthogonal to the array direction of the slidable contact surface of the finger feeding slope 42b is protruded.
