摘要:

PROBLEM TO BE SOLVED: To provide a composite sheet which has high liquid permeability and is excellent in flexibility and gas permeability.

Openings 6 are formed in parts which are not joined to the first sheet 2 and positioned opposite to the projections 5 of the second sheet 3. The openings are preferably formed in the projections 5 of the first sheet 2.
