Abstract: The present invention discloses a trash bag with a holder which comprises a bag having a smaller diameter portion at its open end, and a ring member having an external shape which is wider than the smaller diameter portion of the bag, wherein the bag is fastened to the ring member. In fastening the bag to the ring member, the ring member is first inserted into the bag edgewise, and the bag is then caused to erect upright relative to the face of the ring member with the bottom thereof positioned upwards. Afterwards the bag is caused to move downwards to pass through the interior space of the ring member while it is turned inside out.
