PROBLEM TO BE SOLVED: To provide an improved jitter detection device capable of detecting jitter. SOLUTION: The jitter detection device is equipped with a reception circuit 1 for receiving a signal, a determination circuit 3 for determining a signal portion used for jitter detection in the received signal based on a signal amplitude, and a jitter detection circuit 5 for detecting jitter on the signal based on the determined signal portion. The determination circuit 3 includes the first threshold setting circuit for generating the first threshold, the second threshold setting circuit for generating the second threshold, and a period signal generation circuit for generating a period signal by using the first and second thresholds, and the jitter detection circuit 5 includes a signal portion detection circuit for detecting the signal portion by responding to the received signal following the period signal.
