Abstract: A novel vinyl-group-containing fluorene compound and a method for producing the same, a polymerizable monomer and cross-linking agent including the compound, a leaving-group-containing fluorene compound, a monovinyl-group-containing fluorene compound, and methods for producing the same. The vinyl-group-containing fluorene compound is represented by formula (1) in which W1 and W2 represent a group represented by formula (2), a group represented by formula (4), a hydroxyl group, or a (meth)acryloyloxy group, R3a and R3b represent a cyano group, a halogen atom, or a monovalent hydrocarbon, and n1 and n2 are integers of 0-4. In formulas (2) and (4), (Z) is an aromatic hydrocarbon ring, X is a single bond or a group represented by —S—, R1 is a single bond or a C1-4 alkylene group, R2 is a substituent such as a monovalent hydrocarbon, and m is an integer of 0 or more).
