Abstract
[Objective] To provide a ceramic emitter that exhibits high radiation intensity and excellent wavelength selectivity. [Solution] A ceramic emitter includes a polycrystalline body that has a garnet structure represented by a compositional formula RAlO(R: rare-earth element) or RGaO(R: rare-earth element) and has pores with a porosity of 20-40%. The pores have a portion where the pores are connected to one another but not linearly continuous, inside the polycrystalline body.
