Abstract: A light emitting device (1) includes (i) a surface-mounted light emitting section (10a), (ii) a lens section (30) which is provided on a light exit side of the surface-mount light emitting section (10a), and (iii) a frame section (40) which fixes a periphery of the lens section (30). In the surface-mounted light emitting section (10a), a resin layer (17) that contains a red fluorescent material (17b) covers at least one (1) blue LED chip (14a). This allows the surface-mounted light emitting section (10a) to emit (i) light that matches a peak wavelength which falls within a short wavelength range and (ii) light that matches a peak wavelength which falls within a long wavelength range.
