[Problem] To accurately detect a multipath wave at high speed. [Solution] This multipath detection device 10 comprises an observation value acquisition unit 20, an estimation value calculation unit 30, and a determination unit 40. The observation value acquisition unit 20 receives a positioning signal from each of a plurality of positioning satellites, and obtains an observation value of a carrier wave phase of each positioning signal. The estimation value calculation unit 30 calculates an estimation value corresponding to the observation value on the basis of a geometric distance obtained from the position of the positioning satellite and an approximate position of an antenna ANT1. The determination unit 40 determines whether the received positioning signal is a multipath wave on the basis of the amount of temporal change of the observation value and the amount of temporal change of the estimation value.
