Abstract: A sensor unit includes a light emitting element that emits light toward an object, two light receiving elements that receive light from the object, and a transmissive window that is disposed between the light emitting element and the object and transmits light emitted from the light emitting element. The two light receiving elements are disposed so as to be positioned on a circle concentric with the light emitting element and to be positioned in a range of less than 180 degrees around the light emitting element.
