Abstract
In a mirror surface state detection device, a light-emitting element obliquely irradiates the mirror surface of a mirror with light. A light-receiving element is arranged adjacent to the light-emitting element to have an optical axis almost parallel to that of the light-emitting element and a tilt angle almost equal to that of the light-emitting element and receives scattered light of the light emitted from the light-emitting element. A condensation detection unit detects the state on the mirror surface on the basis of the scattered light received by the light-receiving element. A moisture detection device is also disclosed.
