A silicone member used for a micro device and a micro device which achieve both electrification suppression and light transmittance are provided. The silicone member is used as a micro device and has a holding part for holding samples, or defines the holding part through the combination with a counterpart member. The silicone member includes a silicone material which has silicone and an ionic conductive agent, and the content of the ionic conductive agent is 0.01 part by mass or higher and 1 part by mass or lower with respect to 100 parts by mass of the silicone. The micro device includes the silicone member.

The object of the present invention is to provide a conductive roll having high resistance to permanent set and high resistance to adhesion. The conductive rollhas a rubber elastic portion formed of a rubber material including a carbon-carbon double bond and exhibiting electric conductivity. The surface of the rubber elastic portion is exposed as the surface of the roll. An organic group including one or more groups selected from silicone groups and fluorine-containing groups is bonded through an isocyanuric acid skeleton to the surface of the rubber elastic portion. The organic group may be a group derived from an organic compound including one or more groups selected from silicone groups and fluorine-containing groups and having a carbon-carbon double bond.
