PURPOSE: An error detection device in data transmission is provided to increase stability and rate of data transmission by detecting error and retransmitting correct data. CONSTITUTION: A transmitting unit(210) transmits error signal and retrial signal with transmission data. A data recording unit(220) records error signal and retrial signal with transmission data. An error detection unit(230) detects error signal and retrial signal, and transmits an elimination signal to the data recording unit(220) if it recognizes error signal and retrial signal, so data in error is eliminated in the data recording unit(220). A receiving unit(240) receives no erroneous data from the data recording unit(220). If data transmission is completed, the receiving unit(240) transmits completion signal to the error detection unit(230).
