## Abstract

A surface protection composition which is hard to deform or flow even placed under environments of a large temperature change with an external physical load such as pressure, and which stably protects a metal surface. A terminal fitted electric wire coated with the composition. The surface protection composition contains a high-consistency material (A) containing a lubricant base oil and an amide compound, and a phosphorus composition (B). The phosphorus composition (B) contains a composition (b1) containing one or more compounds represented by the general formulae (1) and (2) and one or more metals and/or one or more amines. The phosphorus composition (B) also contains one or more compounds (b2) represented by the general formula (3).
