PROBLEM TO BE SOLVED: To provide an optical cable for indoor wiring which can be wired not only in an indoor corner part but also in a flat plane part like a floor face. SOLUTION: In an optical indoor cable which comprises a wiring member 1 made by covering an optical fiber 2 with a synthetic resin, the wiring member 1 constituted by juxtaposing the optical fiber 2 and a tension member 3 of the optical fiber 2 and covering them with the synthetic resin is formed into such a shape that the cross-section is a substantial triangle and, at the same time, such a cutting groove 5 as to easily separate the vertex part 4 of the triangle of the wiring member 1 and form a trapezoidal cross-section is drilled.
