PROBLEM TO BE SOLVED: To provide a sheet for a bedding which can be efficiently attached to and detached from the bedding, and of which the washed seal can be thrown into between two roles of a role finish machine in a state stretched as flat as possible (a state without unevenness or wrinkle), and does not react to a sensor. SOLUTION: In a state mounted on the bedding such as a mattress, the sheet comprises a one side covering face for covering the surface facing the side of the user of the bedding and another side covering face turning to the back face positioned on the opposite side of the surface facing the user side from the side face of the bedding. In the sheet for the bedding in which an opening for putting the bedding in and out of another side covering face is formed, at least corner parts of another side covering face are formed with an elastic material in which folds are not formed in a shrunken state. In a state not mounted on the bedding, the elastic material forming at least corner parts of another side covering face becomes a shrunken state, and one side covering face and another side covering face become flat in an adhesion state.
