A packaging device for inserting a sheet-shaped product group, in which a plurality of sheet-shaped products are stacked in the thickness direction of the sheet-shaped products, from a mouth part of a packaging bag body into the packaging bag body, and sealing the mouth part. This invention has: a pushing-in mechanism for pushing in the sheet-shaped product group from the mouth part of the packaging bag body towards the bottom part of the bag body while causing the sheet-shaped product to slide, and thereby inserting the sheet-shaped product group into the bag body; a closing mechanism for pulling the mouth part of the bag body, in a state in which the sheet-shaped product group has been inserted, towards both sides of an intersecting direction intersecting with the direction in which the pushing-in mechanism pushes in the sheet-shaped product, and thereby closing the mouth part; and a sealing mechanism for sealing the mouth part in a state of being pulled by the closing mechanism.
