To provide an object detector that can detect better than an existing object detector can.SOLUTION: When the distance acquisition condition is satisfied, a detected distance acquisition part 301 acquires a detected distance based on an output of a distance measuring sensor 21. When the distance acquisition condition is not satisfied, on the other hand, an estimated distance acquisition part 302 acquires an estimated distance based on a relative moving state acquired by a vehicle rate sensor 22, for example, and the past detected distance acquired by the detected distance acquisition part 301. When the distance acquisition condition is not satisfied includes when the distance measuring sensor 21 has not received reception waves with intensities not smaller than the threshold value and the distance measuring sensor 21 having received reception waves with intensities not smaller than the threshold value does not make the distance acquisition condition satisfied.SELECTED DRAWING: Figure 3 【課題】従来よりも良好な物体検知が可能な物体検知装置を提供する。【解決手段】距離取得条件が成立した場合、検出距離取得部３０１は、測距センサ２１の出力に基づいて検出距離を取得する。一方、距離取得条件が不成立の場合、推定距離取得部３０２は、車速センサ２２等によって取得された相対移動状態と、検出距離取得部３０１によって取得された過去の検出距離とに基づいて、推定距離を取得する。距離取得条件が不成立の場合は、測距センサ２１にて閾値以上の強度の受信波が受信されなかった場合の他に、測距センサ２１にて閾値以上の強度の受信波が受信されたにもかかわらず距離取得条件が不成立の場合をも含む。【選択図】図３
