PROBLEM TO BE SOLVED: To secure sufficient keystroke even when a key top side surface part is formed so as to suspend from an apex peripheral edge of a key top toward a base plate, in a so-called isolation keyboard.SOLUTION: A keyboard includes: a plurality of keys; a base plate 39 for supporting each key; and a frame 41 arranged so as to rise substantially vertically with respect to the base plate, and surrounding each of the keys. Each key includes a key top 32 which is pressed and operated. The key top has: a key top apex 33; and a key top side surface part 34 suspended from a peripheral edge of the key top apex toward the base plate. At a portion corresponding to a lower end part of the key top side surface part of the base plate, a hole part 39h is formed in which the lower end part of the key top side surface part can be inserted from above. In a pressed-state where the key top is pressed and operated, the lower end part of the key top side surface part is inserted in the hole part. |
