A half mirror having an arbitrary shape on an arbitrary substrate and excellent in appearance and design, and a manufacturing method thereof. The manufacturing method of the half mirror which concerns on this invention is a transparent substrate or the base material composition containing the addition polymeric compound which has three or more reactors, the addition polymeric compound which has an acidic group, and the addition polymeric compound which has a hydrophilic functional group. The organic film formation process of apply | coating on a transparent film, superposing | polymerizing, and forming an organic film, the metal salt formation process which makes the said acidic group a metal (M1) salt, and the metal (M2) which is lower in ionization tendency than the said metal (M1) ion By treating with a metal (M2) ion aqueous solution containing ions, a metal fixing step of using the metal (M1) salt of the acidic group as a metal (M2) salt, and reducing the metal (M2) ions to reduce the organic film. It includes a reduction step of forming a metal film on the surface. |
