Abstract
An optical component and an electrical board that have a low coefficient of linear expansion and small mold shrinkage, a method for producing the optical component, and a method for producing the electronic board are provided. An optical component includes a polymer having a repeating structural unit represented by general formula (1) where R1 and R2 each independently represent —H or —CH3; m and n each independently represent an integer in the range of 0 to 3; asterisk denotes a dangling bond that bonds to one of Xa and Xb; and —H bonds to the other one of Xa and Xb.
