PROBLEM TO BE SOLVED: To provide a binary-phase signal phase detector capable of acquiring an estimated phase and an estimated angular velocity free from ripple components resulting from amplitude nonuniformity between binary signals.SOLUTION: A binary-signal phase detector 1 comprises: a component separator 2 separating a binary-phase signal constituted by a sin&phgr; signal and a cos&phgr; signal into a positive phase component and a reverse phase component using a DDSRF or a complex filter equivalent to the DDSRF on the basis of an estimated phase &thetas; ; and a phase and angular velocity estimator 4 compensating for a q-axis signal Vof the positive phase component of the binary-phase signal (sin&phgr; signal and cos&phgr; signal) separated by the component separator 2 using a feedback control compensator to acquire the estimated phase &thetas; and an estimated angular velocity ω of the positive phase component, and outputting the estimated phase &thetas; to the component separator 2.
