[Object] To ensure a wear measurement over an entire section of a trolley wire and to facilitate the wear measurement, and also to perform the measurement during daytime, without being affected by structures existing around the trolley wire. [Means to solve] A line sensor 5 and an illumination lamp 6, which are placed in a direction of a scanning line perpendicular to a laying direction of a trolley wire, are mounted on a test car 1. The line sensor 5 shoots a pantograph contact surface of the trolley wire by the running of the test car, and this image signal is saved in a recording device 8 through a measurement computer 7. The measurement computer 7 arranges luminance signals of scanning lines, obtained by the line sensor 5, in time series, and creates a line sensor image. The measurement computer 7 gets a binary operated line sensor image from this line sensor image. The measurement computer 7 further removes sky parts from this binary operated line sensor image and detects edges of a trolley wire worn portion, then determines a width of the trolley wire worn portion through an overall width of the trolley wire and a height, viewed from the line sensor, of the trolley wire.
