1. A resin composition comprising:
an acrylated lignin formed by chemical bonding a compound containing an acryl group or a methacryl group to a phenolated lignin, wherein the phenolated lignin containing a repeating unit represented by the following general formula (I):

OG Complex Work Unit Chemistry
wherein
R1 to R5 are each independently a monovalent group selected from H, OH, a C1 to C6 alkyl group, a C1 to C6 alkoxy group, and a C6 to C10 aryl group, or adjacent substituents among R1 to R5 form a substituted or unsubstituted aromatic ring together,
at least one of R1 and R2 is a hydroxyl group, and R6 is OCH3 or H, and
the phenolated lignin contains a repeating unit having a syringyl skeleton in which R6 is OCH3 in the general formula (I), at a mole fraction of 40% or more when a total molar amount of repeating units in the phenolated lignin is taken as 100%.
