PROBLEM TO BE SOLVED: To provide a non-contact temperature sensor capable of preventing the increase in man-hour and cost at the manufacturing time, the reduction in productivity, and the deterioration in work environment and natural environment and also capable of suppressing a sensitivity error and a reduction in sensitivity.SOLUTION: A non-contact temperature sensor 100 includes: a guide cylinder 30 provided so as to define a visual field range of the temperature detection by an infrared ray detection heat-sensitive element 15 in a heat source 7A. The guide cylinder 30 includes: an opening P; and a body part 31 including sloped wall parts 31a to 31b to extend slope-wise against the perpendicular direction of a light receiving surface N toward the light receiving surface N arranged with the infrared ray detection heat-sensitive element 15 from the opening P, and further includes a light-shielding space W formed by the body part 31 around a light receiving range Q including the infrared ray detection heat-sensitive element 15. |
