FILTER ELEMENT AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a filter element which shows a low level of loss in air permeation pressure and a high dust collecting efficiency and also has an antistatic function and non-self-adhesive properties as well as a manufacturing method for a filter element. SOLUTION: This filter element is characterized in that a porous surface layer 2 is formed of a raw material containing a vulcanized product of a fluororubber and, if necessary, a fluororesin 3 and a conductive substance, applied to the surface of a filter element with voids which is obtained by sintering a resin particle 1. Also the manufacturing method for the filter element is provided.
