PROBLEM TO BE SOLVED: To provide a bag whose opening part can be opened largely by bending the side face of the bag to a lower part on the outer side at the lower position of the opening edge part of a housing part and exposing the entire opening edge part when a slide fastener on an upper surface is opened. SOLUTION: In the bag composed of an upper surface part, both side face parts, both gusset parts and a bottom surface part, the upper surface part forms a lid part openable and closable through the slide fastener from the upper surface to the upper surfaces of both gusset parts. Both side faces are switched to two upper and lower stages, a raising piece is provided on the inner side of the switching part and the upper end edge of the raising piece is turned to the opening edge part of both side faces in the housing part.
