Abstract

A pushbutton includes a key top, including a light-transmissive display part, the key top configured to be depressed; and LEDs configured to emit light toward the display part. The display part includes a bottom surface and a sloped surface, the sloped surface being continuous with an outer edge of the bottom surface and broadening outward as the sloped surface progresses upward from the bottom surface. The light emitted from the LEDs toward the display part is reflected by the sloped surface and emitted toward the exterior from a top surface.
