A plug for a living body includes a first chamber, a second chamber communicating with the first chamber, a holding means for holding the condition that the volume of the first chamber is reduced and a fluid put into the first and second chambers. The fluid is pressed into the second chamber when the volume of the first chamber is reduced so that the volume of the second chamber is increased. The external auditory miatus can be surely plugged with the plug.
