To provide a stacking device for plate members capable of reducing noises occurring when the plate members used for electrolytically refining non-ferrous metals such as copper and lead are stacked.

This device for stacking anode scraps S on a turn table 4 so that one end edges and the other end edges thereof are alternately aligned with each other includes a conveying means 2 for conveying the anode scraps S near the turn table 4 and a moving means for moving the anode scraps S from the conveying means 2 onto the turn table 4. The moving means includes a moving mechanism for moving the anode scraps S from the base ends to the distal ends of a pair of slide rails 5, 5 and an inclination mechanism 3 for guiding the anode scraps S moved by the moving mechanism onto the turn table 4 in the inclined state. The pair of slide rails 5, 5 are configured so that the distal ends thereof are vertically swingable about the base ends thereof, respectively, and comprise swing means 6 for swinging the distal ends of the pair of slide rails 5, 5, respectively.
