A method for producing a rubber composition include a mixing step, a drying step, and a dispersion step. In the mixing step, an aqueous solution that includes at least one of oxycellulose fibers and cellulose nanofibers is mixed with rubber latex to obtain a first mixture. In the drying step, the first mixture is dried to obtain a second mixture. In the dispersion step, the second mixture is tight-milled using an open roll to obtain a rubber composition. The rubber composition does not include an aggregate that includes at least one of the oxycellulose fibers and the cellulose nanofibers, and has a diameter of 0.1 mm or more.

The present invention reduces the minimum detectable volume of a piece of a glove in the detection using a metal detector. A glove made of a rubber or resin film which contains magnetic particles, wherein the quantity of the magnetic particles is 0.2 to less than 40 mass % relative to the whole of the film; and the magnetic particles comprise secondary particles formed by the agglomeration of primary particles.
