The insulating layer of the porous member is formed by that the water-in-oil type emulsion is coated so as to form a thin film as a coated film, the thermosetting liquid solventless varnish as the oil is polymerized and cured after the formation of the thin film, and the water drops as the water is dried and removed after the curing of the thermosetting liquid solventless varnish.
