PROBLEM TO BE SOLVED: To provide an abrasion measurement apparatus of a trolley wire which measures an abrasion and a deflection of the trolley wire by using a single apparatus. SOLUTION: The apparatus includes: a line sensor image creating section 4a for aligning images captured by a line sensor 2 in chronological order, and creating a line sensor image; a determination/analysis/binarization processing section 4b for implementing a binarization processing of the line sensor image, and creating a binarized line sensor image; a trolley wire abrasion portion edge detecting section 4d for detecting edges on both sides of an abrasion portion in the binarized line sensor image; a trolley wire barycentric position detecting section 4e for detecting a barycentric position of the trolley wire from positions of the edges on both sides of the abrasion portion; a trolley wire deflection actual coordinate conversion calculating section 4f for detecting the actual deflection of the trolley wire from the barycentric position of the trolley wire; and a trolley wire abrasion portion width calculating section 4g for detecting the abrasion of the trolley wire in parallel with at least the processing by the trolley wire deflection actual coordinate conversion calculating section 4f.
