Abstract: A conductive paste composition includes: carbon black having a porous structure and having a DBP oil absorption amount of greater than 240 mL/100 g and a specific surface area of greater than 350 m2/g; and a liquid silicone rubber base composition, in which in a case where the conductive paste composition is dried and cured at 180° C. for two hours to form a conductive film, a content of the carbon black in the conductive film is 4% by mass or greater and 24% by mass or less, and a surface resistance of the conductive film is 1 k? or greater and 9 k? or less.

Abstract: An anti-tack liquid Q1 is produced by an anti-tack liquid production device, using an anti-tack agent G for unvulcanized rubber in the form of a solid having a moisture content that is more than 3% by mass but is 35% by mass or less, wherein the aforementioned device includes: a hopper 11 for storing the anti-tack agent G for unvulcanized rubber; a stirring tank 13 for mixing water and the anti-tack agent G for unvulcanized rubber; and a quantitative feeder 12 for quantitatively supplying a constant amount of the anti-tack agent for unvulcanized rubber from the hopper 11 to the stirring tank 13.
