Abstract
A swallowing sensor that is attached to a person's pharyngeal portion and that measures the person's swallowing ability includes: a film-shaped detector that detects vibration based on displacement and sound of the pharyngeal portion; an adhesive layer that is provided on one of two main sides of the detector and that attaches the detector to the pharyngeal portion; and a sensing film arranged on the detector to cover entirety of the other main side of the detector, wherein a main side of the sensing film that contacts the detector contains an adhesive component, the sensing film is attachable to the pharyngeal portion around the detector using the adhesive component, and the sensing film conveys vibration to the detector. Accordingly, the swallowing ability can be more accurately measured.
