A breathing mask includes a rigid member, an elastic member, and a foam member. The rigid member has an interface on the side away from the user's face for accessing the breathing gas of the continuous positive airway pressure device, and a flared joint on the side adjacent to the user's face. The elastic member is in communication with the inner cavity of the rigid member and is fixedly connected to the flared joint. The side of the elastic piece adjacent to the user's face at least partially abuts the user's nasal bridge area to form an elastic body part, and a support part connected to the elastic body part is provided on the side of the elastic member adjacent to the user's face. The foam member is fixed to the support part and, together with the elastic member, forms a sealing surface for fitting the user's face.
