To provide a chip conveyor apparatus which employs a novel plate board shape configured not to draw in chips once discharged from an outlet.

When plate boards 2, 2 turn around at a sprocket, a rear end edge 23f on the bottom surface side of a convex part 23 of one plate board rotates not to exceed a front end edge 22e on the chip carrying surface side of a concave part 22 of another plate board; and a rear end edge 23e on the chip carrying surface side of the convex part 23 of the one plate board reaches a position that exceeds a front end edge 22f on the bottom surface side of the concave part of the another plate board.
