PROBLEM TO BE SOLVED: To provide a layered optical member which reduces necessity of wiping an adhesive as far as possible and can easily wipe the adhesive even when performing the wiping, in the layered optical member such as an optical low-pass filter or a beam splitter. SOLUTION: The layered optical member has reservoir parts (J) of the adhesive 19 on the peripheral part of a quartz plate (12) and on the peripheral edge part of an optical plate (13). Further, an infrared ray-cut thin film (14) is formed and is adhered with the adhesive (19). COPYRIGHT: (C)2008,JPO&INPIT
