Conductor and connector

It is aimed to provide at a conductive path is formed by connecting the front end of a covered wire with a rear end of a connector, receiving the front end of the coated wire along with the connector in a housing, even if an outer diameter of the coated wire is large. A conductor track (20) by connecting a covered wire (26), in which a conductor (27) by an insulating coating (28) is enclosed, is formed with a rear end of a connector (21), and the entire connector (21) and a front end of the coated wire (26) in a housing (10) receivable. The conductor track (20) includes a coating layer (29) made of a light-curing resin, which is formed in an area of ​​the coated wire (26) which is accommodated in the housing (10) that are thinner than the insulating coating (28) and a enclosing portion of the conductor (27) on which the insulating coating (28) is removed.
