摘要 |
Platelike first transparent members 321 and platelike second transparent members 322 are prepared. Each first transparent member has substantially parallel first and second surfaces (film forming surfaces). A polarization splitting film 331 is formed on the first film forming surface. A reflecting film 332 is formed on the second film forming surface. The films are not formed on the surfaces of the second transparent members 322. A plurality of the first transparent members 321 and a plurality of the second transparent members 322 are adhered alternately. A block is cut from the so-adhered transparent members at a prescribed angle to the surfaces and the cut surfaces thereof are polished to obtain a polarization beam splitter array 320.
