철도 차량용 대차의 전극 부착 판스프링의 제조 방법은, 도전성 섬유를 수지에 함유시킨 섬유 강화 수지를 가지는 판스프링의 상기 섬유 강화 수지의 표면에 부분적으로 레이저 광을 조사하여 상기 수지의 일부를 제거하여 상기 도전성 섬유 일부를 노출시키는 수지 제거 공정과, 상기 섬유 강화 수지에서 상기 도전성 섬유의 일부를 노출시킨 노출 영역에 전극을 설치하는 전극 형성 공정을 포함한다. A method of producing an electrode-equipped plate spring of a railcar bogie includes: a resin removing step of partially irradiating a surface of fiber-reinforced resin, prepared by including electrically conductive fibers in resin, of a plate spring with a laser beam to partially remove the resin and partially expose the electrically conductive fibers; and an electrode forming step of attaching an electrode to an exposed region formed by partially exposing the electrically conductive fibers of the fiber-reinforced resin.
