PLUMBING APPARATUS

To provide a technique capable of enhancing the design freedom of a sensor device when constituting a limited reflection type photoelectric sensor.SOLUTION: In a plumbing apparatus with a sensor device, the sensor device includes: a photoelectric sensor 52-A capable of detecting an object to be detected by receiving the reflected light of the detection light projected from a light projecting unit 64 by a light receiving unit 66; a light projecting substrate 54 on which a light projecting element 68 constituting the light projecting unit 64 is mounted on a first mounting surface 54a; and a light receiving substrate 56 on which a light receiving element 72 constituting the light receiving unit 66 is mounted on a second mounting surface 56a. As the light projecting substrate 54 and the light receiving substrate 56 are separated from the first mounting surface 54a and the second mounting surface 56a, a first normal line La extending outward from the first mounting surface 54a and a second normal line Lb extending outward from the second mounting surface 56a are arranged to be close to each other.SELECTED DRAWING: Figure 6 【課題】限定反射型の光電センサを構成する場合に、センサ装置の設計上の自由度を高められる技術を提供する。【解決手段】センサ装置を備える水回り機器であって、センサ装置は、投光部６４から投光した検知光の反射光を受光部６６で受光することで被検知物を検知可能な光電センサ５２−Ａと、投光部６４を構成する投光素子６８が第１実装面５４ａに実装される投光用基板５４と、受光部６６を構成する受光素子７２が第２実装面５６ａに実装される受光用基板５６と、を備え、投光用基板５４と受光用基板５６は、第１実装面５４ａ及び第２実装面５６ａから離れるにつれて、第１実装面５４ａから外方に延びる第１法線Ｌａと第２実装面５６ａから外方に延びる第２法線Ｌｂとが互いに近づくように配置される。【選択図】図６
