A bulk component feeder includes a conveying channel 42 through which the electronic components P are conveyed, a ventilation channel 43 that is formed along the conveying channel 42, and a partition 44 by which postures of the electronic components P conveyed through the conveying channel 42 are maintained and by which the conveying channel 42 is separated from the ventilation channel 43. The conveying channel 42 communicates with the ventilation channel 43 through an upper part 45 of the partition 44. It is possible to increase a size of an air channel A which acts as a flow channel for airflow and through which the electronic components P are conveyed with no respect to sizes of the electronic components P, thus, a desirable conveying speed is assured even though the conveyed electronic components P are micro-components.
