PROBLEM TO BE SOLVED: To provide paper formed of different fibers per different region on the same plane of the paper, and a method for producing the same.SOLUTION: There are provided the paper having a paper-made transparent window of single-ply paper, and the method for producing the same. The paper has a plurality of different regions formed of different fibers on the same plane at desired positions and with desired shapes without depending on a papermaking direction. In addition, the paper has the transparent window which is not a conventional transparent window of multilayer paper and comprises a first region 2 including at least first fibers and a second region 3 including at least second fibers different from the first fibers at a desired position in the first region. |
