Abstract: Disclosed is a process of preparing a composite wire which comprises sealing one end of a pipe to be employed as a jacket, inserting a bar to be employed as a core into the pipe and conducting a hot processing of the pipe while vacuum-sucking the pipe from the other end thereof. In accordance with the present invention, the strength of the resulting composite wire is sufficient, and the number of operations can be reduced, that is, the wire can be prepared under the excellent workability and productivity.
