A drip bag which has a simple structure with hook members adhered to the outer surfaces of two opposing face sheets of a bag body is configured to increase the opening area of an opening of the bag body and stabilize the shape of the opening. To cope with this, a drip bag 1 has a bag body 2 formed of a water permeable filtering sheet 20 and having an upper end to be opened, and hook members 10 formed of a thin plate-shaped material and provided on outer surfaces of two opposing face sheets of the bag body 2. The hook member 10 includes: an upper stuck part 12 which is adhered to the bag body 2 along the opening 3 of the bag body 2; a center part 13 which is located below the upper stuck part 12 at the center of the bag body 2 in the width direction thereof and formed so as not to be pulled out from the bag body 2; and a hook part 11 not adhered to the bag body 2. A pair of first oblique folding lines L1 and a pair of second oblique holding lines L2 are formed on the upper stuck part 12 by respective specific angles. |
