Abstract: A housing unit includes: a linear material; and a housing body that houses the linear material. In the housing body, winding regions in which the linear material is wound are disposed in a circumferential direction. The linear material is wound in a figure eight in a first region pair constituted by a pair of the winding regions. The linear material is wound in a figure eight in a second region pair constituted by a pair of the winding regions that are different from the winding regions constituting the first region pair.

Abstract: A method of exposing a core of an optical fiber cable that includes: a core including an optical fiber; a wrapping tube wrapping the core; a jacket housing the core and the wrapping tube; and a tension-resisting member of a Fiber Reinforced Plastic (FRP) embedded in the jacket, includes: making a cut in a circumferential direction in the jacket at a position closer to a first end portion of the optical fiber cable than to a second end portion of the optical fiber cable in a longitudinal direction; bending the optical fiber cable at a portion having the cut and fracturing the tension-resisting member; and removing a removal portion of the jacket that is disposed between the cut and the first end portion.
