The present invention provides a nostril plug (A1) which can reduce functional articulatory disorder by closing a nostril thereby preventing the leaking of exhalation from the nostril and can be used with substantially no discomfort. The nostril plug (A1) being inserted into a nostril for suppressing the leaking of exhalation from a nose includes a valve unit (14) for suppressing only passage of exhalation in breathing and support bodies (11, 12) for supporting the valve unit (14) mounting the valve unit thereon and being arranged in the nostrils. The support body (11, 12) is formed of a tubular body inscribed in the nostril, and the valve unit (14) is removably fitted in the support bodies (11, 12). When the pressure in the nostril reaches a predetermined level or more through exhalation, the valve unit (14) can be separated from the support bodies (11, 12) by the pressure.
