A bulk feeder including a storage section storing multiple electronic components in a loose state and a supply passage guiding the electronic components stored in that storage section to an electronic component supply position while arranged in a single line. The supply path, as well as arranging electronic components stored in the storage section in a single line by relying on magnetic force of permanent magnets, includes a magnetic force dependent supply passage for indexing from the storage section, and an air pressure dependent supply passage indexing electronic components indexed from the magnetic force dependent supply passage to the supply position by relying on positive pressure or negative pressure air blown from air passages. By combining the appropriate advantages of magnetic force and air pressure respectively, it is possible to perform supply of electronic components ideally and practicality of the bulk feeder is improved.
