摘要： A stretchable cable is provided that allows an extra length to be reduced when routed in a movable part. The stretchable cable includes an elastically deformable hollow insulation having a hollow portion that is continuous along a cable longitudinal direction, and at least one electricity- or light-conducting wire-shaped body provided in a spiral shape along the cable longitudinal direction and fixed to the hollow insulation to stretch and contract together with the hollow insulation. The cable is elongated not less than 1.2 times when a tensile force is applied, and the cable returns to an original length when the tensile force is removed.

摘要： A peripheral surface-emitting linear light guide is provided with an optical fiber including a core, an outer peripheral surface of which is exposed from a cladding at one end in a longitudinal direction, and a light-scattering member that covers an entire periphery of the outer peripheral surface of the core in an exposed portion over a predetermined axial length range. The light emitted from the outer peripheral surface of the core is scattered and radiated by the light-scattering member. The light-scattering member includes a light transmissive base material having a higher refractive index than the core and light-scattering particles that scatter the light incident on the base material, and the light-scattering particles are dispersed and mixed in a certain proportion throughout the base material. At least a portion of the light-scattering member in the longitudinal direction is an increasing portion whose thickness increases gradually toward a tip side of the core.
