To provide a contact force measurement method, etc., capable of further accurately measuring a contact force between a slider body and an overhead power line in a simple structure in a current collector comprising the slider body of a flexural plate type.SOLUTION: A current collector comprises: a slider body 30 including a plurality of slider pieces 31 abutted to an overhead power line T and arrayed in a tie direction; a connection member 40 which connects the slider pieces and has flexibility; a plurality of connection member support parts 52 and 60 supporting a plurality of parts of the connection member discrete in the tie direction; a load transmission member 51 to which ends of the connection member support parts are connected; and a collector head 10 mounted to the load transmission member in collector head mounting parts 12 and 13 disposed separately from the connection member support parts in the tie direction. A method of measuring contact force between the slider body and the overhead power line comprises: measuring distortion in a region between the collector head mounting part and the connection member support part in the load transmission member; and the calculating a contact force using the distortion.SELECTED DRAWING: Figure 1
