Provided are a sheet transport apparatus and a sheet transport method preventing false detection of multiple feeding when feeding sheets of different thicknesses. The sheet transport apparatus includes an ultrasonic sensor including an ultrasonic transmitter and an ultrasonic receiver disposed opposite each other across a sheet transport path, a type detector for discriminating between a first sheet and a second sheet thicker than the first sheet while one or the other of the sheets is being fed along the transport path, and a multiple feed detector for detecting the presence or absence of multiple feeding of sheets along the transport path, based on an output produced by the ultrasonic sensor and on a detection result supplied from the type detector.
