To provide a separator for electronic components easy to reduce its thickness and excellent in mechanical strength, dimensional stability, and heat resistance; and to provide a method for manufacturing the separator capable of providing uniform porous structure and excellent in productivity.
The separator is a porous film, containing filler particles with a melting point of 180°C or above or no substantial melting point, which is made of a resin compound with a glass transition point of 180°C or above. The method for manufacturing the separator for electronic components which forms a porous film by coating on a base material and drying a paint containing a resin compound with a glass transition point of 180°C or above, filler particles with a melting point of 180°C or above, at least one of good solvents which dissolves the resin compound well, and at least one of poor solvents which dissolves the resin compound little.
