UIMID of a UIM 50 owned by the owner of a portable phone 40 is stored in an owner information registration area 410b of phone 40. This composition shows an excellent chemical and physical stability. The first radiation-permeable layer contains a first dielectric material. When the iris area extraction unit extracts an iris area from the collation eyeball image, the collation pattern generating unit generates a collation iris pattern image by performing polar coordinate transformation of an image in the extracted iris area. As a result, the difference between images caused by the thickness difference in the wafer can be tolerated and the false information generation prevented without adversely affecting the sensitivity.
