<P>PROBLEM TO BE SOLVED: To provide a raindrop detecting device capable of detecting an accurate temperature of the inner surface of a windshield. <P>SOLUTION: A raindrop detecting substrate 22 of a raindrop detecting part 20 provided in a raindrop detecting device 1 is provided with a first light emitting element 23, a second light emitting element 24, a light receiving element 25, and an ECU 26 which are mounted on it. The raindrop detecting substrate 22 is attached to a position at a distance from an outer surface 101 of a windshield 10. A humidity detecting substrate 33 of a humidity detecting part 30 is provided with a windshield temperature element 31, an in-vehicle temperature element 32 and an in-vehicle humidity element 34 which are mounted on it. The humidity detecting substrate 33 is attached in such a manner that the windshield temperature element 31 comes into contact with an inner surface 102 of the windshield 10. Consequently, the windshield temperature element 31 can accurately detect the temperature of the inner surface 102 of the windshield 10 without being affected by heat generated at the ECU 26 of the raindrop detecting part 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
