To provide a quantitative feeder for resin pellets capable of preventing damage to a guide member.

The quantitative feeder for resin pellets is constituted so that the resin pellets supplied to an annular passage 6 are transferred to a discharge port 8 by the rotation of a turntable 5 and quantitatively supplied from the discharge port 8 by the guide member 7 arranged on the horizontal surface 5b of the turntable 5 (in the annular passage 6). In this quantitative feeder for resin pellets, the clearance C between the guide member 7 and the vertical surface 5a of the turntable 5 is set to a size 1.2-1.6 times the maximum length of each of the resin pellets.
