For enabling a measurement of configuration of a wearing portion of a trolley wire from a traveling car, easily. Slit laser beams L1 and L2 are irradiated on the trolley wire 1, approximately vertical to a progressing direction of the car 9, from means provided on a roof there. Irradiation of the laser beams produces a light cut-off image in a lower side of the trolley wire 1, including a side surface thereof. Upon receipt of the light of this light cut-off image, obliquely from the lower thereof, by means of a camera or the like, there are obtained images, for presenting the configuration of the trolley wire 1 on a lower side thereof, including a side surface thereof, i.e., a profile "d0" of the light cut-off image of the trolley wire 1. With provision of two (2) sets of those, each including such light projecting portion and light receiving portion therein, at positions separating from each other, along left and right direction of deviation of the trolley wire 1, the configuration of the portions, upon which the laser light beams L1 and L2 hit, can be measured, and then by treating an image processing thereupon, there can be produced data for presenting cross-section configurations of the trolley wire 1, on a sliding surface and the left-hand and the right-hand side surfaces thereof. Upon basis of the data produced, for presenting cross-section configurations of the trolley wire 1 on a sliding surface and the left-hand and the right-hand side surfaces thereof, a residual amount and an amount of wear are measured on the side surface of the trolley wire 1.
