A symbol synchronization device that enables effective symbol synchronization establishment and synchronization holding for an arbitrary spread code sequence. The device includes (i) a primary demodulation section for receiving a spread modulation signal where chips for symbol synchronization are added to a symbol data after spread modulation, and demodulating the spread modulation signal to a base band spread modulation signal, (ii) symbol synchronization chip removal means for removing chips for symbol synchronization from the base band spread modulation signal, (iii) a secondary demodulation section for despreading the base band spread modulation signal from which the chips for symbol synchronization are removed, (iv) a symbol timing regeneration section for regenerating a symbol timing by performing in-phase addition of the base band spread modulation signals; and (v) a symbol decision section for deciding the symbols for the despread signals that are output from the secondary demodulation section, synchronizing with the symbol timing.
