PROBLEM TO BE SOLVED: To provide a parts feeder capable of stably conveying parts, while easily obtaining a desirable amplitude. SOLUTION: In this linear parts feeder 300, a weight part 302 and a piezoelectric vibration part 303 provided over a base part 301 give vibration to a first and a second conveying passages 310 and 320 through a plurality of driving plate springs 390 and a plurality of vibration preventing plates springs 380 so as to convey fine parts 800 on the first and the second conveying passages 310 and 320. A horizontal vibration transmitting member 360b fixed to a projection part 375 of a fixed plate 370 gives horizontal vibration to a third conveying member 350 for circulating the fine parts 800 transferred by the first and the second conveying passages 310 and 320, and a component force elastic plate member 360a gives horizontal vibration and vertical vibration to the third conveying member 350.
