Conduction path and connector

The purpose of the invention is to provide a conduction path wherein the front end of a covered wire is connected to the back end of a terminal metal fitting, such that the front end of the covered wire, together with the terminal metal fitting, can be housed inside a housing even when the conductor of the covered wire has a large external diameter. The conduction path (20) has a configuration wherein the covered wire (26), which is formed by surrounding the conductor (27) with an insulating cover (28), is connected to the back end of the terminal metal fitting (21), the entirety of the terminal metal fitting (21) and the front end of the covered wire (26) being housed inside the housing (10). The conduction path (20) is provided with a photo-curing resin cover layer (29) which is provided in a region of the covered wire (26) to be housed inside the housing (10), is thinner than the insulating cover (28), and surrounds a region of the conductor (27) wherefrom the insulating cover (27) has been removed. 在将被覆电线
