A track circuit state determination apparatus (100) includes measurement terminals (200) provided at section boundaries between track circuits and a processing apparatus (300). The processing apparatus (300) calculates a current vector of transmission current to transmission voltage in each track circuit, and divides the calculated current vector into a segment of a period in the presence of an on-rail train and a segment of a period in the absence of an on-rail train. The processing apparatus (300) compares the current vector locus in each period with a reference vector locus based on past current vector loci of the corresponding track circuit to determine the state of the track circuit including at least one of a normal state and an abnormal state.
