An electro-oculography measuring device includes: an electro-oculography measuring unit configured to measure an electro-oculography original signal a view capturing unit configured to capture a view picture a drift estimation processing unit configured to estimate a drift signal and a subtractor which subtracts the drift signal from the electro-oculography original signal to output an electro-oculography signal, and the drift estimation processing unit includes: an electro-oculography change amount calculating unit configured to calculate an electro-oculography change amount a motion vector estimating unit configured to estimate a motion vector of a moving object included in the view picture a drift change amount estimating unit configured to estimate a drift change amount assuming that a change in a gaze direction follows a motion of the moving object and a drift estimating unit configured to estimate the drift signal by adding the drift change amount to a past drift signal.
