The invention provides a component feeder can effectively prevent the jamming of a cover tape in a discharge path. A carrier tape wound in advance on a reel held at a specified position is sequentially delivered and transported to the downstream side. A cover tape is peeled off the tape body of carrier tape that has reached a peeling position, and a component stored in the recess of the tape bodyis exposed. Then the component is supplied to the pick up position on the downstream side while the cover tape that has been peeled is wound on a rotor provided on a specified position. The rotor is rotated in synchronous with delivery of the carrier tape. So the cover tape is delivered while applied with tension, and discharged to the downstream side by way of the discharge path on the rotor exitside. A discharge guide provided with a first main surface guide part and a second main surface guide part of which an interval gradually increases from the vicinity of the rotor toward discharging direction, is arranged on the main surface sides of the cover tape discharged to the discharge path.
