To provide an intake device capable of improving intake efficiency and suppressing deterioration of a sensor.SOLUTION: An intake device for filtering and guiding intake air to an internal combustion engine, includes a filter casing 20 provided with an air filter for filtering the intake air, and an intake passage 2 for making the intake air pass from an upstream side to a downstream side of the air filter housed inside, and further having a conductive downstream-side passage wall portion 220 exposed to the intake passage 2 at the downstream side with respect to the air filter, and an air physical amount sensor 30 having a sensor element detecting a specific physical amount relating to the intake air at a downstream side with respect to the air filter, and constituting an earth structure 36 for earthing the sensor element in a state of being conductively connected to the downstream-side passage wall portion 220.SELECTED DRAWING: Figure 2

    【課題】吸気効率を向上させ、センサ劣化を抑制する吸気装置の提供。【解決手段】内燃機関への吸入空気を濾過して案内する吸気装置は、吸入空気を濾過するエアフィルタと、内部に収容したエアフィルタの上流側から下流側へ吸入空気を通過させる吸気通路2を、形成しており、エアフィルタよりも下流側にて吸気通路2に露出している導電性の下流側通路壁部220を、有するフィルタケーシング20と、吸入空気に関連した特定物理量をエアフィルタよりも下流側にて検出するセンサ素子を、有し、下流側通路壁部220と導通接続された状態にてセンサ素子をアースするアース構造36を、構築している空気物理量センサ30とを、備える。【選択図】図2
