The present invention provides a light guide plate and an input apparatus. The light guide plate includes a light guide body, at least one first opening structure, and at least one second opening structure. The first opening structure passes through the light guide body and includes at least one first closed end. The second opening structure passes through the light guide body and includes at least one second closed end. The first closed end and the second closed end face each other. The first closed end partially overlaps the second closed end on at least one first axis, the first closed end and the second closed end are disposed parallel to each other on at least one second axis, and the first axis is substantially perpendicular to the second axis.
