Abstract

The present invention relates to a porous sheet and a method for manufacturing the porous sheet. A porous sheet including a fine-fiber web layer and a support layer and a method for manufacturing the same are provided, and it is possible to implement a porous sheet with sufficient strength and thickness to be used in peeling and laminating processes of a multilayer ceramic capacitor.

Claims13

Dependent claims

A porous sheet comprising:

a fine-fiber web layer consisting of fine-fibers with a diameter of 50 to 5000 nm;
and
a support layer having the fine-fiber web layer coupled to one or both surfaces thereof.

Dependencies are inferred from the claim text.
