a mask body that defines a communication hole;
a sensor mounting portion that extends from a front surface of the mask body and surrounds the communication hole, the sensor mounting portion defining an installation space therein;
a seal coupled to a rear surface of the mask body and configured to define a breathing space between the mask body and a user;
a pressure sensor accommodated in the installation space and configured to sense air pressure inside the breathing space that is in communication with the communication hole;
a film disposed in the installation space and configured to restrict permeation of moisture from the breathing space into the installation space through the communication hole; and
a sensor sealing member configured to apply pressure to the film,
wherein the sensor sealing member comprises:
a cover portion that covers an opening defined at a front surface of the sensor mounting portion, and
an extension portion that extends from a rear surface of the cover portion and is configured to apply pressure to the film, and
wherein the pressure sensor and the film are directly adjacent to each other in the installation space.
