Abstract
A medium includes a base layer and a separation layer. First to fifth regions are defined in the medium along a first direction in this order. Portions of the base layer which are in contact with the separation layer are stickable in at least a part of the first region and the fifth region and are not stickable in the second region and the fourth region. A length, in a second direction, of a second-side end portion of the fifth region in the first direction is less than a length, in the second direction, of a first-side end portion of the third region in the first direction. A length, in the second direction, of a first-side end portion of the fifth region in the first direction is less than the length, in the second direction, of the second-side end portion of the fifth region in the first direction.
