A hopper is provided with which damages of articles can be suppressed without lowering the processing speed. A hopper (4) includes a first hopper main body (40), and a first gate (G1). A first inner surface (41) of the first gate (G1) forms a collecting space (A1) for holding articles with the first hopper main body (40), and stores articles in the interior of the collecting space (A1) when in theclosed state and discharges articles by turning to open. The first inner surface (41) includes a first upper slanted surface (S2) and a first lower slanted surface (S3) that are continuous. An angleformed by the first lower slanted surface (S3) and the horizontal plane is smaller than an angle formed by the first upper slanted surface (S2) and the horizontal plane.
