A wheel position detection apparatus is applicable to a vehicle in which four wheels provided with tires are attached to a vehicle body, and is provided with sensor transmitters and a receiver. The sensor transmitters each include an acceleration sensor and a first control portion that detects the position of the corresponding wheel on the basis of the acceleration thereof, and creates and transmits a frame in which data indicating the result of the wheel position detection are stored. The receiver is provided in the vehicle body, and includes: a receiving portion that receives each transmitted frame by means of a receiving antenna; and a second control portion that identifies whether the sensor transmitter that has transmitted each frame is attached to the right wheels or the left wheels, from among the four wheels.
