PROBLEM TO BE SOLVED: To provide a rain sensor with high light collection efficiency, which is provided with a second reflective plate having multiple focal points to allow the rain sensor to be used with any automobiles requiring different focal points depending on thickness of glass parts thereof.SOLUTION: A rain sensor of the present invention is provided with a multifocal second reflective plate configured to receive entire reflection light totally reflected by a glass part with different phases that depend on thickness of the glass part, allowing the reflection light irradiated over a large area to be collected thereby, the second reflective plate also being configured to re-reflect the reflection light coming in from horizontal and vertical directions and focus the same onto a photoreceiver.SELECTED DRAWING: Figure 2

    【課題】多数の焦点を有する第2反射板を提供してガラス部の厚さによって相異なる焦点を要求する如何なる自動車にも適用できる、 高い集光効率を有するレインセンサーを提供する。【解決手段】本発明によるレインセンサーは、ガラス部の厚さにより位相差をもって全反射される反射光を全部受光する多焦点の第2反射板を提供することで、広い領域に照射される反射光を集光させ、水平方向及び垂直方向に流入される反射光を再び反射して受光部に集光させる第2反射板の構成を含むことを特徴とする。【選択図】図2
