Abstract
An iodine-PVA polarizing element 30 μm thick is dried by heating at 50° C. for 30 minutes to thereby obtain a polarizing element having a moisture content of 4.9% by weight. A pair of 100 μm-thick norbornene resin films (tradename 'ARTON' made by JSR Corporation) used as protective films are stuck to opposite surfaces of the obtained polarizing element through layers of PVA adhesive agents which are applied on the pair of nonbornene resin films respectively and dried, to form, a polarizer.
