The high-property, high-precision color filter has an active film layer formed on a transparent substrate and comprised of at least one or more of active alumina or active silica, and fine patterns in the form of dot, stripe, and/or other patterns formed on the active film layer by a dye of any desired color being taken up into fine holes in the active film layer, and further an overcoat layer placed on the active film layer and having no affinity to the dye. In the method for manufacture of the color filter, the step of forming the fine patterns comprises mounting a metal mask having specified patterns holes on the active film layer, mounting a transfer sheet having an ink layer containing a dye on top of the active film layer, and subsequent heating in an atmosphere of reduced pressure. According to the invention, it is possible to obtain a color filter having excellent properties, including smoothness, heat resistance, water resistance, and light-resistance, and fine patterns in three colors, red green, and blue, having excellent spectral properties, and which can be manufactured by a simple process.
