A wire harness includes: an electrical wire including a core wire and an insulating covering for covering the core wire; and a sheet material in which the electrical wire is disposed on a resin main surface, and a part of the main surface having contact with the electrical wire is thermally processed with the insulating covering of the electrical wire, thereby forming an electrical wire fixing part. A part of the sheet material including the electrical wire fixing part is softer than the insulating covering.

A surge arrester and a method for manufacturing the surge arrester are disclosed. The surge arrester includes a preassembled active part extending in a longitudinal direction, and a separately produced flexible housing defining a bore in the longitudinal direction and having an opening at an end surface of the flexible housing. The flexible housing is arranged surrounding the active part via the bore and in contact with the active part. The contact causes a deformation of the flexible housing in a circumferential direction, and the deformation generates a pressure applied on the active part along a radial direction.
