A wiring member includes: a wire-like transmission member including a transmission wire body and a covering for covering the transmission wire body; and a sheet member having a main surface on which the wire-like transmission member is disposed and fixed to the covering by direct fixation to hold the wire-like transmission member. In a portion where the sheet member and the covering are fixed to each other by direct fixation, the sheet member is bended along a periphery of the covering wholly in a thickness direction to wrap the wire-like transmission member.

Provided is a process for the manufacture of a mineral-insulated socket, especially as a module for the manufacture of an electrical feedthrough and especially for use in an exhaust gas duct of a motor vehicle. The mineral-insulated socket has a metallic inner part arranged in a metallic outer pipe and electrically insulated from this metallic outer pipe by an electrically insulating, mineral material. In a process, the metallic inner part, the electrically insulating material, and the outer pipe are compressed to form a composite and in a subsequent step, the mineral-insulated socket is produced by removing at least one complete section of the compressed composite.
