を特徴とする自動車用雨滴センサ。A light emitting element is installed inside the windshield and emits high-frequency infrared rays substantially in front of the vehicle through the windshield, and a light emitting element is installed inside the windshield to detect reflected components of the infrared rays that are diffusely reflected by falling raindrops in front of the windshield. Raindrops are detected by extracting only the high-frequency components corresponding to the above-mentioned infrared rays from the light-receiving element and the detection output of the light-receiving element. A raindrop sensor for an automobile, comprising a bandpass filter that outputs a signal corresponding to the amount of raindrops, and wherein the light receiving element is installed at a position where it does not receive the component of the infrared rays reflected by the windshield.
