The present invention relates to a CRT socket having a connection terminal for connecting a cathode ray tube (CRT) and a cathode ray tube (CRT) socket substrate, and more particularly to a cathode ray tube (CRT) socket substrate for an 8-pin CRT socket board to a 9-pin Brown's electron gun connection pin. The CRT socket board of the present invention can be used as a CRT socket board of a conventional 8-pin CRT socket. (CRT) socket substrate can be used as it is. Further, since the CRT socket substrate can be used as it is, the manufacturing cost is not added, and consequently the production cost can be reduced. In addition to the conventional CRT socket substrate, (CRT) socket configured to maintain the socket substrate manufacturing process.
