Abstract
To provide a temperature sensor probe that can take stable measurements, and a manufacturing method thereof. The temperature sensor probe related to the present invention is a temperature sensor probe for measuring temperature using a fluorescent substance that changes fluorescent characteristics depending on temperature. Then, a powdered fluorescent substance, a guide wave route member that propagates excitation light, which is irradiated on the fluorescent substance, and fluorescent light, which is produced by the fluorescent substance, are provided. Further, the particle size of the powdered fluorescent substance is confined to the range of 60 to 100 μm.
