摘要：
An aqueous adhesive for rubber includes rubber latex and an ammonium-salt-based vulcanization acceleration aid. An amount of the ammonium-salt-based vulcanization acceleration aid contained in the aqueous adhesive is preferably not less than 0.01% by weight and not greater than 5.0% by weight in terms of solid content. An aqueous adhesive for a ball includes rubber latex as a main component. A content of an inorganic filler in the aqueous adhesive is not greater than 0.1% by weight in terms of solid content. A ball 2 includes a hollow core 4 obtained by crosslinking a rubber composition that contains a vulcanizing agent. The core 4 is formed of two hemispherical half cores. The two half cores are adhered to each other by using the aqueous adhesive for a ball.
