Provided is a wavelength converting member made of a sintered body which inhibits color unevenness of exit light after wavelength conversion and has excellent light emitting efficiency and inhibited decrease in mechanical strength. The wavelength converting member includes a plate-like sintered body having one principal surface as a light entrance surface and the other principal surface opposite to the entrance surface as a light exit surface, in which the plate-like sintered body has a porosity of 0.1% or less which has fluorescent material grains containing an activator and light-transmitting material grains, the entrance surface and the exit surface are a sintered surface in which the fluorescent material grains and light-transmitting material grains are exposed without processing. |
