An LED module includes a submount having a face in a thickness direction thereof, an LED chip bonded to the face of the submount with a first bond, and a patterned wiring circuit electrically connected to the LED chip. The first bond transmits light emitted from the LED chip. The submount is a light-transmissive member having light diffusing properties, and a planar size larger than a planar size of the LED chip. The patterned wiring circuit is provided on the face of the submount so as not to overlap the LED chip. The submount is constituted by a plurality of light-transmissive layers which are stacked in the thickness direction and have different optical properties so that a light-transmissive layer of the plurality of light-transmissive layers which is farther from the LED chip is higher in reflectance in a wavelength range of the light emitted from the LED chip. |
