A rain sensor with a multi-sensitivity region includes: at least one light emitting unit configured to output light; a reflective plate provided to correspond to the at least one light emitting unit at a position spaced apart from the at least one light emitting unit by a predetermined distance; a glass part configured to reflect light reflected by the reflective plate and form a plurality of sensing regions; and a light receiving unit configured to receive the light reflected by the glass part. The reflective plate includes at least one first reflective unit forming a first sensing region and at least one second reflective unit forming a second sensing region, the second sensing region has a quantity of light per unit area higher than a quantity of light per unit area of the first sensing region, and the at least one light emitting unit is disposed at a position corresponding to a focal distance of each of the at least one first reflective unit and at least one second reflective unit.
