A device is disclosed for detecting a frame synchronous signal which has been applied to a communication system for indicating a starting point of transmitted data. The frame synchronous signal detector includes a parallel converter, a detector, and a buffer. The parallel converter sequentially divides parallel data into segments. The detector compares data of each of the segments with the data of the frame synchronous signal which has been mapped, and from this comparison, precisely detects the data of the frame synchronous signal even though data having an abnormal format is inputted.
