Summary:PROBLEM TO BE SOLVED: To obtain a holding device by which an errorless and stable measured value can be acquired when ultraviolet rays by sunlight are measured by installing a fixation base or the like which shaft-supports a support base which holds an ultraviolet(UV) sensor so as to be freely rotatable. SOLUTION: A support base 1 which holds a UV sensor is shaft-supported by a fixation base 3 so as to be freely rotatable, and UV sensors are inserted into a recessed part 111 and a recessed part 111 on its upper plate 11. In the case of a manual operation, a rotating plate 41 is turned so as to be positioned in such a way that the support base 1 is directed to the direction of the sun, i.e., that the sun's rays are crossed at right angles to the longitudinal direction of the upper plate 11 at the support base 1. Then, a rod-shaped body 13 is monitored. When a shadow is recognized on the upper plate 11, a supporting and bearing plate 12 is turned until the shadow is not recognized. When the shadow disappears, the UV sensors are directed vertically to the sun. The sun is moved with the passage of time, and the shadow of the rod-shaped body 13 appears. Then, the supporting and bearing plate 12 is turned again so that the shadow disappears.
