Abstract
The present invention relates to a ceramics composite including an inorganic material which includes: a matrix phase including a translucent ceramics; and a phosphor phase including YAG containing Ce, in which a content of the phosphor phase is from 22% by volume to 55% by volume based on the whole phase including the matrix phase and the phosphor phase, a content of Ce in the YAG is 0.005 to 0.05 in terms of an atomic ratio of Ce to Y (Ce/Y), and the ceramics composite has a thickness in a light outgoing direction of 30 μm to 200 μm.
