Abstract
A single crystal of 3-(2-furyl)methacrylic acid anhydride, PA1 (a) which has an absorption edge in a region off light having a wavelength of not more than 450 nm PA1 (b) which exhibits non-linear optical activity, PA1 (c) which has a single crystal structure having a size of which the largest side is at least 1 mm long, and PA1 (d) which consists of 3-(2-furyl)methacrylic acid anhydride off the following formula (I). ##STR1## This single crystal of FMA is useful as a material for manufacturing a light wavelength conversion element, an optical switch element or the like.
