Abstract
A glove includes a glove main body for covering a wearer's hand, the glove main body containing nitrile-butadiene rubber as a principal component, wherein: the glove main body comprises zinc oxide, a vulcanizing agent, a vulcanization accelerating agent, and a cross-linked product from the nitrile-butadiene rubber and polycarbodiimide; a mass ratio of the polycarbodiimide to the nitrile-butadiene rubber is no less than 0.003 and no greater than 0.1; a mass ratio of the zinc oxide to the nitrile-butadiene rubber is no less than 0.010 and no greater than 0.05; and a MEK-absorption capacity of the glove main body is no greater than 25 times the glove main body on a mass basis. The percentage content of a MEK-insoluble matter in the glove main body is preferably no less than 65% by mass. The molar ratio of zinc oxide to the carbodiimide group in the polycarbodiimide is preferably 1 to 50.
