Claim:
1. A method of producing a formed article having a base and a layer formed on the base and obtained by implanting ions of a hydrocarbon compound into a polyorganosiloxane compound-containing layer, the base being formed of a material selected from the group consisting of polyimides, polyamides, polyamideimides, polyphenylene ethers, polyether ketones, polyether ether ketones, polyolefins, polyesters, polycarbonates, polysulfones, polyether sulfones, polyphenylene sulfides, polyallylates, acrylic resins, cycloolefin polymers, and aromatic polymers, the method comprising implanting ions of a hydrocarbon compound into a surface of a polyorganosiloxane compound-containing layer of a formed body that includes the polyorganosiloxane compound-containing layer in its surface, wherein the hydrocarbon compound is selected from the group consisting of an alkene gas, an alkadiene gas, an alkyne gas, a cycloalkane gas and a cycloalkane gas, wherein the formed article has a low water vapor transmission rate of 0.15 to 2.80 g/m2/day, wherein the main chain structure of the polyorganosiloxane compound is a straight chain structure shown by the following formula (a), a ladder-like structure shown by the following formula (b), or a polyhedral structure shown by the following formula (c), wherein Rx, Ry, and Rz individually represent a hydrogen atom, a non-hydrolysable group selected from the group consisting of a substituted alkyl group whose substituent is halogen atoms, a hydroxyl group, a thiol group, an epoxy group, a glycidoxy group, an unsubstituted phenyl groups, a substituted alkenyl group whose substituent is halogen atoms, a hydroxyl group, a thiol group, an epoxy group, a glycidoxy group, or an unsubstituted phenyl groups; an unsubstituted alkenyl group; a substituted aryl group whose substituent is halogen atoms, alkyl groups having 1 to 6 carbon atoms, alkoxy groups having 1 to 6 carbon atoms, a nitro group, a cyano group, a hydroxyl group, a thiol group, an epoxy group and a glycidoxy group, provided that a case where both Rx in the formula (a) represent a hydrogen atom is excluded.
