PROBLEM TO BE SOLVED: To obtain a master batch, which does not generate any acidic gas at the time of kneading and melting, by melt mixing a chlorine atom-free thermoplastic resin capable of being melt molded at a specified temperature, an F-containing anti-fogging agent, and a basic inorganic compound. SOLUTION: There are melt mixed, preferably, 100 parts by weight of a chlorine atom-free thermoplastic resin capable of being melt molded at 150 to 230 deg.C and, preferably, containing 80 wt.% or over of a polyolefin resin and/or an ethylene-vinyl acetate resin; preferably, 1 to 70 parts by weight of an F- containing anti-fogging agent; and, preferably, 0.01 to 14 parts by weight of a basic inorganic compound (e.g. calcium carbonate), which is in the form of a powder, preferably, having a particle size of 0.1 to 10μm. The ratio by weight of the basic inorganic compound to the F-containing anti-fogging agent is preferably at 0.005 to 0.2. The F-containing anti-fogging agent includes, for example, one which is obtained by reacting a fluoroalkyl group-containing epoxy compound with a compound having one or more OH groups in the molecule in the presence of an acid catalyst such as BF3 or the like, etc.
