To provide a living body detection device that can more reliably determine the presence of a living body, has an improved appearance around a ceiling of a passenger compartment, and prevents erroneous determination due to affection of external light.SOLUTION: A room lamp 7 is attached to a ceiling of a passenger compartment, the room lamp 7 comprising: a light source 15; and a lamp housing 11 having a lens cover 21 and covering the light source 15 from at least a passenger compartment side so as to transmit light from the light source 15 to the passenger compartment side through the lens cover 21. A radar module 23 comprises: an antenna part 29 which is covered with the lamp housing 11 from the passenger compartment side, and which emits a wave and receives a reflected wave from a target of the wave; and a control unit 31 for, on the basis of the reflected wave received by the antenna part 29, identifying displacement of a surface of the object and determines presence of a living body in the passenger compartment on the basis of the identified displacement.SELECTED DRAWING: Figure 4
【課題】生体検知装置が生体の有無をより確実に正しく判定できるようにするとともに、車室の天井周りの見栄えを良好にし、かつ外光の影響による誤判定を防止する。【解決手段】車室の天井には、光源15と、レンズカバー21を有し、レンズカバー21によって光源15の光を車室側に透過させるように光源15を少なくとも車室側から覆うランプハウジング11とを有するルームランプ7が取り付けられ、レーダーモジュール23は、ランプハウジング11によって車室側から覆われ、かつ電波を発射して電波の対象物からの反射波を受信するアンテナ部29と、アンテナ部29により受信した反射波に基づいて、対象物の表面の変位を特定し、特定した変位に基づいて、車室内における生体の有無を判定する制御部31とを備えている。【選択図】図4
