To provide a printed circuit board feed device for feeding one printed circuit board at a time to a conveyance path in a stable manner, even in the case where there is warp on the printed circuit board.

The printed circuit board feed device approaches the lower part under a printed circuit board 10 located at the bottom and retreats from there. In approach, the feed device holds a plurality of printed circuit boards 4 from both sides together with a support member 2, which supports the plurality of printed circuit boards 4 at the lower part, and releases them. The feed device at least includes a pair of holder members 3 holding the printed circuit board located at the bottom, which is supported by the support member 2, and a hammering member that strikes at least the printed circuit board located at the bottom from the side, out of the plurality of printed circuit boards 4 held by the holder member 3. The lower edge of the holder member 3 is designed to hold the printed circuit board located at the bottom up to less than 50% of the thickness from the top surface of the printed circuit boards 4.
