A timing synchronous detection device includes: a first autocorrelator that performs autocorrelation using a received signal and a first delay signal in which the received signal is delayed; a second autocorrelator that performs autocorrelation using the received signal and a second delay signal in which the received signal is delayed; an average-normalization device that obtains an average value of an output signal of the first autocorrelator and an output signal of the second autocorrelator; a comparator that compares the average value and a threshold value and that outputs, if the average value is larger than the threshold value, the average value; and a maximum value search device that searches for a maximum value of the average values that are output from the comparator.
