The vehicle-use object detection apparatus includes a plurality of ultrasonic sensors mounted on a vehicle, each of the ultrasonic sensors being configured to receive a reflected version of an ultrasonic wave transmitted by itself and not to receive reflected versions of ultrasonic waves transmitted by the other ultrasonic sensors, a first determination means to make a determination whether an object is present around the vehicle based on the received reflected versions of the transmitted ultrasonic waves when a first detection condition is satisfied, and a second determination means to make a determination, for each of the ultrasonic sensors, whether there is adhesion of snow around the ultrasonic sensor based on an echo wave received by the ultrasonic sensor when a second detection condition different from the first detection condition is satisfied.
