PURPOSE: To obtain a laminate which is formed by laminating a water-soluble liquid compsn. exhibiting a dew point phenomenon between substrates and at least part of which is transparent and which more surely maintains a sealing function by not providing the sealing part with a specific layer.

CONSTITUTION: The laminate, which is formed by laminating the water-soluble liquid compsn. which exhibits the dew point phenomenon (e.g.: aq. soln. of water- soluble high polymer, such as partially acetylated matter of PVA, polyvinyl methyl ether, methyl cellulose or polyethylene oxide) 3 between the substrates 1, 2 and at least a part of which is transparent, is not provided with an exothermic layer 4 at the point of at least the sealing part 5. Then, the laminate capable of surely exhibiting the sealing function by maintaining the permeation of water molecules as a solvent at a min. level in spite of org. sealing and attaining the function and purpose safely with lessened energy without generating a clearance as a curtain function is obtd.
