A polymerizable compound represented by general formula (1):

wherein Z 1 and Z 2 each represent a (meth)acryloyloxy group; X 1 and X 2 each independently represent a single bond, an optionally branched alkylene group having 1 to 8 carbon atoms, an ether linkage, -COO-, -OCO-, -OCOO-, a 6-membered ring optionally having a substituent, or a combination thereof; R 1 represents -R', -OR', -CO-R', or -OCO-R'; R' represents a halogen atom, an optionally branched alkyl group having 1 to 8 carbon atoms, or a 6-membered ring optionally having a substituent, L 1 and L 2 each independently represent a member selected from a single bond, -CH 2 CH 2 -, -CH=CH-, -C≡C-, -CH 2 O-, -OCH 2 -, -COO-, and -OCO-; m represents an integer of 1 to 4; and the R 1 's may be the same or different.
