Abstract
A vertical keyboard, which is used with key top pressing direction set to a substantially horizontal direction, includes a housing having opening portions into which the key tops are fitted. A lower internal surface of the opening portion is inclined with respect to a direction perpendicular to the surface of the housing, in a downward direction from the keyboard interior toward the keyboard surface side. This can reduce adhesion or accumulation of dust or dirt in a space between the lower internal surface of the opening portion and the lower internal surface of the key top.
