Abstract: The disclosed light-emitting module (40) is provided with: an LED chip (42); a sheet-shaped phosphor layer (44) which is arranged so as to face a light emitting surface (42a) of the LED chip (42), and which converts the wavelength of the light emitted by the LED chip (42); and a filter layer (46) which, among the surfaces of the phosphor layer (44), is formed on at least either the side surface or the surface facing the LED chip (42), and which allows the light emitted from the LED chip (44) to pass through, and reflects the light of which the wavelength has been converted by the phosphor layer (44). The filter layer (46) is constructed so that, relative to the total energy of the outgoing light, the proportion of the outgoing light energy which is within plus or minus 60 degrees from the frontal direction is at least 80%.
