PROBLEM TO BE SOLVED: To provide a polarizing element with a large birefringence and excellent transmittance for blue light by a simple and inexpensive method for manufacturing the polarizing element. SOLUTION: A plurality of prism sheets are formed by stretching and working an organic material with translucency and birefringence such as PET (polyethylene terephthalate) into a specified shape with continuous defined shapes. A prism sheets laminated body is formed by laminating the prism sheets in such a way that the prism sheets with respectively different optic axes are brought into contact with each other. The polarizing element is made of an optical block laminated body, with a specified shape obtained by cutting and quarrying out the laminated body.
