PROBLEM TO BE SOLVED: To solve the problem that a conventional solar radiation sensor is turned to be defective since the adhesion of a light receiving element holder and a condensing lens is peeled at a removing work from an instalment panel in maintenance. SOLUTION: In this solar radiation sensor 1, at least a part of a holding mounting part 4a of a condensing lens 4 is provided with a notched part 4b, and a flange 3a is exposed on the outer peripheral side face as the mounting part. Thus, it is possible to prevent the generation of any accident that the solar radiation sensor is turned to be defective when a removing tool such as a driver 30 is suspended from the holder mounting part 3a with any stress applied, and the adhesion of the light receiving element holder 3 and the condensing lens 4 is peeled as a result.
