Polarizer having non-polarizing part

Provided is a polarizer having a non-polarization portion with reduced shape unevenness. The polarizer of the present invention is a polarizer having a non-polarization portion, in which the non-polarization portion has a shape matching degree of 0.05 or less. In such polarizer, the number of portions where the shape of the non-polarization portion is distorted is small. Accordingly, when the non-polarization portion of the polarizer is used as, for example, a portion corresponding to a camera portion of an image display apparatus, alignment processability is improved and hence the alignment of the camera can be satisfactorily performed.
