Provided is a laryngeal mask that enables an airway to be accurately secured by a simple procedure. The laryngeal mask is provided with an outer tube (4a) and a connector (5), having a base end in which is formed a first connecting portion (5b) capable of being connected to an artificial respirator and a leading end in which is formed a ventilation opening, the outer tube (4a) and the connector (5) having a communication passage formed therein that communicates between the first connecting portion (5b) and the ventilation opening, a ring-shaped cuff (7) capable of tightly adhering to a tracheal opening of a patient trachea as a result of inflating in a state where the ring-shaped cuff (7) is inserted to a predetermined insertion position, and hyoid bone-contacting portions (6d) and (6e) protruding laterally from the outer tube (4a) so as to contact from above a site in a pharyngeal portion (T) of the patient corresponding to a hyoid bone (J7) of the patient in a state where the ring-shaped cuff (7) is inserted to the insertion position.
