[PROBLEMS] A light source module, surface area light-emitting unit, and surface area light-emitting device that have versatility, where installation work is simplified and production costs are reduced, and where irregularity of light emission and color is sufficiently suppressed. [MEANS FOR SOLVING PROBLEMS] The light source module has a light direction-converting optical element (29) and an LED (28). The light direction-converting optical element (29) has a recess (290) with a light incident surface (29A) into which light enters, a light reflecting surface (29B) for reflecting light entered from the light incident surface (29A), and a light emitting surface (29C) for emitting to a side the light reflected by the light reflecting surface (29B). The LED (28) is placed in a recess (290) of the light direction-converting optical element (29) with a gap provided in between them and applies light to the light incident surface (29A).
