To provide a tape measure capable of measuring distance, with respect to an opposed face by bringing the tape measure into face contact with a plane, and also capable of measuring the outside diameter of an article.

When one rising-up side of a tape measure case is brought into face contact with one sidewall face, by making a cross angle of a base in a side opposite to a gate way of a steel tape in the tape measure case with the one rising-up side into 90°, the steel tape is extended along an extended line direction of the base brought into 90° with respect to the face, the shortest distance up to the opposed wall face is easy measured, a measured value sandwiched between a hook in a tip of the steel tape and a jaw thereof is not stored, when the jaw projected from the tape measure case is provided in the underside of the gate way of the steel tape, and a full scale is copied to a material to be worked.
