POLARIZABLE MOLDED BODY

A polarizable compact is provided with high productivity, which makes a polarizing sheet resistant to the occurrence of color unevenness and voids and also resistant to the occurrence of variations in polarization degree accompanying thermal shrinkage and the like of a protective layer (protective film). A polarizable compact (10) is used for glasses. An injection-molded portion (15) made of a transparent plastic material is thermally bonded to the concave surface side of a polarizing sheet (11) having a predetermined curvature radius. The polarizing sheet (11) has a polarizer layer (13) held between first and second protective layers (17, 19) respectively serving as a convex surface side and a concave surface side. Both the first and second protective layers (17, 19) are formed from transparent films by a casting method with retardation (Re) ‰¤ 50 nm. The transparent films for the first and second protective layers are respectively formed from an acylcellulose-based film and a polyamide-based film. In addition, the second protective layer (19) is directly fused to the injection-molded portion (15).
