PROBLEM TO BE SOLVED: To provide a sensor device that can be made uniform in luminance.SOLUTION: There is provided a sensor device 1 including a light source 2, a sheet type light guide body 3 on which light from the light source 2 is made incident to be guided in a plane direction, and a detection sensor 21 provided opposite one surface of the light guide body. On a surface 27a of the detection sensor 21, a main reflection region 11 and a low reflection region 12 having lower light reflectivity than the main reflection region 11 are formed, and the low reflection region 12 is at least partially at a position closer to the light source 2 than the main reflection region 11. |
