A drip bag which has a simple structure with hook members adhered to the outer faces of two opposing surfaces 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, this drip bag 1A 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 faces of two opposing surfaces 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 to be in an elongated shape; a center part (first center stuck 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; and a hook part 11 not adhered to the bag body 2. A pair of oblique folding lines L1a and L1b are formed on the upper stuck part 12 with a center line disposed therebetween, the oblique folding lines L1a and L1b being more spaced from the center line while extending from a lower portion to an upper portion of the upper stuck part 12, the center line bisecting the bag body 2 in the width direction thereof. A vertical folding line L2 is formed downwardly from immediately below a lower end of the oblique folding lines L1a and L1b. |
