When adhering the color filter 13 to the color filter 13, since the dye 1012 that forms the adhesion surface of the color filter 13 is flat and uniform, the pressure applied during adhesion is directly transmitted as stress to the entire surface of the solid state 1 image element 14 through the adhesive. Solid-state image sensor 14
This has caused damage to the diffusion layer of the solid-state imaging device, resulting in defects in the image quality of the finished solid-state imaging device.

できる。(Function) The color filter for a solid-state image sensor of the present invention has a protrusion on the periphery of a dye film formed on one surface of a substrate, and is bonded to the solid-state image sensor via an adhesive, thereby causing stress applied during adhesion. can be received by the convex portion provided on the surface of the pigment film.
[実施例] この発明の一実施例を第1図に基づいて説明する。[Example] An embodiment of the present invention will be described based on FIG.

下した固体描像素子4の片面とを精度よく接着する。In the color filter 3, a thin, flat dye film 2 is provided on one surface of a glass substrate 1, and convex portions 5 are formed at the four corners of the dye film 2. Then, the surface of the pigment film 2 provided with the convex portions 5 is lowered in the direction of the arrow in the figure, and the convex portions 5 are aligned at a specified position just before they contact the surface of the solid-state image sensor 4. , the surface of the dye film 2 and one side of the solid-state imaging element 4 onto which adhesive has been dropped in advance are adhered with high accuracy.

without contacting the effective surface at the center of the adhesive surface of the solid-state monolithic image element 4;
As long as the color filter 3 to be adhered has a shape that is not oblique (lJ1), it may be provided at any position around the periphery.
