Document Type and Number:

Japanese Patent JP3952419

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a manufacturing method for a porous sheet of uniform thickness and provided with high air permeability and superior surface smoothness.
SOLUTION: A manufacturing method comprises the steps of filling ultrahigh- molecular-weight plastic powder in a mold; heating the ultrahigh-molecular- weight plastic powder filling the mold and then cooling to manufacture a porous sintered compact; releasing the porous sintered compact thus manufactured from the mold; cutting the porous sintered compact into the sheet shape to manufacture a porous sheet; and bringing a sheet surface of the porous sheet into contact with a smooth surface of a base for transfer and heat transferring the smooth surface of the base for transfer on the sheet surface.
