<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method of an optical element capable of preventing the occurrence of burrs upon cutting a large-sized body into individual optical elements. <P>SOLUTION: The manufacturing method of the optical element comprises: a process to form a large-sized spacer 4 where surrounding parts 21, each of which surrounds an area with an optical functional surface 32 arranged therein and has a rectangular outer shape, are arrayed at prescribed intervals from one another through a linking part 22 that is arranged so as not to cover the corner parts of the surrounding parts; a process to fill with adhesive 23 a grid-shaped area of the large-sized spacer wherein the linking part is arranged between the surrounding parts, and to place a first large-sized substrate 2 and a second large-sized substrate 3 opposite to each other across the large-sized spacer and bond them to form a large-sized body 1; and a process to cut the area between the surrounding parts of the large-sized body into grid shapes, then, to form the optical element 5 comprising the first substrate having the optical function surface and the second substrate facing the first substrate through the spacer having the surrounding part. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
