PROBLEM TO BE SOLVED: To provide a key-top sheet having unimpaired appearance with peripheral side face portions of each key top invisible from the upper side of a case, even if the key-top sheet is mounted in a curved state on the back surface side of the case, and easily operated by an operator because of same pressing directions of the key tops. SOLUTION: This key-top sheet 10 for push-button switches is made up by forming a plurality of key tops 13 in a film sheet 11 made of a flexible resin film, and mounted in a curved state on a back surface of a case 20 in conformity to the curved surface shape of the curved case 20 back surface. Peripheral side faces 131 of each key top 13 are formed into rectilinear shapes oriented in the direction to depress the key top 13 and oriented in the same direction (vertical direction), with the key top sheet 10 curved and mounted on the back surface of the case 20. |
