PROBLEM TO BE SOLVED: To provide a CCD sensor improving an impact resistance and a yield at a manufacturing time, without deteriorating the optical characteristics. SOLUTION: When an actual lid 11s (O, +c) becomes a protruding curved surface shape at a front surface side by a curved surface (warpage) by molding as shown in Fig. (e) for a reference state shown in Fig. (d), an image surface 11f by the curved surface (warpage) also becomes a protruding curved surface to the front surface side. Accordingly, as shown in Fig. (f), the lid 11s (-d, +c), in which the curved surface (warpage) is provided but its thickness is thinned to dO-Δd, is used, the curved surface of the image surface 11f is compensated, and the image surface curve can be reduced.
