To provide a paper-made product which is provided with a useful function and a high added value by utilizing an epoch-making characteristic of a so-called extendable paper.

The paper-made product is manufactured by fabricating a paper sheet whose breaking elongation at an environment of 23°C and 50%R.H is ≥13% in both longitudinal and transverse directions or a composite paper sheet which is manufactured by using the paper as a base layer and laminating another material layer thereon, by an appropriate fabricating means such as cutting, folding, punching, press molding, pressure forming and vacuum forming, and has a function obtained by plastic deformation giving a twist.
