<P>PROBLEM TO BE SOLVED: To provide a method for producing a wavelength conversion member, which can easily produce a high strength wavelength conversion member. <P>SOLUTION: Preferably a sintered preform 30 is formed by: forming a compact containing an inorganic phosphor and glass powder but not containing a binder; and sintering the compact under reduced-pressure atmosphere. In this case, voids in the sintered preform 30 can be reduced, thereby producing the higher strength wavelength conversion member. The shape of the wavelength conversion member is not particularly limited. Also the wavelength conversion member may be in the form of a plate or rod. Specifically, the wavelength conversion member can be a plate form whose dimensional ratio of length to thickness is 100:1 or larger, for example. <P>COPYRIGHT: (C)2012,JPO&INPIT |
