Abstract
In order to obtain a light emitting module with a less unevenness of luminance, provided is a method for manufacturing a light emitting module comprising: preparing a light emitter and a light-transmissive light guide plate, the light emitter comprising a light emitting element, the light guide plate having a first main surface serving as a light emitting surface from which light is emitted outside and a second main surface located opposite to the first main surface and having a concave portion, the concave portion comprising a side surface and a bottom surface that is smaller than an opening of the concave portion in a cross-sectional view; fixing the light emitter to the bottom surface of the concave portion via a bonding member; and forming a wiring at an electrode of the light emitting element.
