PROBLEM TO BE SOLVED: To provide a mask with a reservoir bag, which prevents clogging at a connection part of a connector tube with the reservoir bag when wearing the mask. SOLUTION: The mask 1 with the reservoir bag includes: a mask body 2 for covering a mouth and a nose; the expansible reservoir bag 3 communicating with the oxygen introduction port 2c of the mask body 2; and the connector tube 4 which is the tube for connecting the oxygen introduction port 2c of the mask body 2 to the reservoir bag 3 and where a connection hole to which an oxygen tube 20 is connected is opened in the middle part. The reservoir bag 3 is formed to have a shape to be stored in a space, which is formed by the jaw lower part, neck part, and clavicle hollows of a dorsally lying person, whose head is not bent backward but kept at a natural position, in a state where the reservoir bag 3 is expanded. Consequently, the reservoir bag 3 is prevented from being bent, and also it is prevented that the communication of oxygen or air with high-concentrated oxygen is blocked between the reservoir bag 3 and the mask body by clogging the connection part with the connector tube 4.
