Abstract
A light-emitting module includes a light-guiding plate having an upper surface with a first hole and having a rectangular shape in a top view, and a light-emitting element opposite to the first hole and disposed opposite to the upper surface. The first hole includes a first portion and a second portion between the first portion and the upper surface. The first portion is provided with a first opening at a boundary between the first portion and the second portion and a first lateral surface inclined with respect to the upper surface. A shape of the first opening in the top view is defined by a first axis parallel to a short side of the rectangular shape of the light-guiding plate and a second axis parallel to a long side of the rectangular shape and shorter than the first axis in a plan view.
