Provided is a sintered phosphor-composite for an LED, having high heat resistance, high thermal conductivity, high luminance, and high conversion efficiency. In addition, there are provided: a light-emitting apparatus which uses the sintered phosphor-composite; and an illumination apparatus and a vehicular headlamp which use the light-emitting apparatus. The sintered phosphor-composite includes a nitride phosphor and a fluoride inorganic binder. The sintered phosphor-composite preferably has an internal quantum efficiency of 60% or more when excited by blue light having a wavelength of 450 nm. Further, the sintered phosphor-composite preferably has a transmittance of 20% or more at a wavelength of 700 nm.
