description A rain sensor according to an embodiment comprises: a substrate; a sensing electrode formed on a first surface of the substrate; a reaction layer formed on the first surface of the substrate and burying an upper surface of the substrate and the sensing electrode; a driving unit electrically connected to the sensing electrode formed on the first surface of the substrate and processing a sensing signal transmitted through the sensing electrode; and a protective layer formed surrounding the driving unit, wherein an impedance value according to a change of at least one of a force and a dielectric constant caused by presence of rainfall is changed, and the sensing electrode transmits the sensing signal with respect to a variation amount of the impedance value of the reaction layer to the driving unit.
