To provide a thermoluminescenece body which has a strong mechanical strength and which is convenient for handling, and further which can be used as a selecting emitter.

As for this thermoluminescence body, its light emitting part 2 is heated by a flame of a candlestick 1, and a rare earth oxide thin film of the heated light emitting part 2 emits light by emitting a strong excited light. As for this thermoluminescence body, this light emitting part 2 is constituted of a substrate to carry the mechanical strength and the rare earth oxide thin film to emit the excited light. For this reason, the thermoluminescence body of the present invention becomes a highly efficient one which is easy to use.
