A polymerizable compound represented by general formula (1):

• [in the formula, P represents a polymerizable functional group and Sp represents a spacer group or a single bond,
• A1, A2, A3, and A4 each independently represent a divalent alicyclic hydrocarbon group or aromatic hydrocarbon group,
• X1, X2, X3, and X4 each independently represent a divalent linking group or a single bond (at least one of X1, X2, X3, and X4 represents one of linking groups selected from —CH2CH2COO—, —CH2CH2OCO—, —COOCH2CH2—, —OCOCH2CH2—, —CH═CH—, —CH═CHCOO—, —OCOCH═CH—, —N═N—, —N═C—, and —C═N—N═C—), wherein a combination of X2 and X3 (hereafter expressed as “X2/X3”) in the general formula (1) is as follows:
• “—COO—(CH2)u—/—CH2CH2—COO—”, “—COO—(CH2)u—/—COO—CH2CH2—”,
• “—COO—(CH2)u—/—OCO—CH2CH2—”, “—COO—(CH2)u—/—CH2CH2—OCO—”,

• “—CH2CH2—COO—/—(CH2)u—”, “—COO—CH2CH2—/—COO—(CH2)u—”,
• “—OCO—CH2CH2—/—OCO—(CH2)u—”, “—CH2CH2—OCO—/—OCO—(CH2)u—”,
• “—CH2CH2—COO—/—OCO(CH2)u—”, “—COO—CH2CH2—/—OCO—(CH2)u—”,
• (u represents an integer of 0 to 2)
• “single bond/—CH2CH2—COO—”, “single bond/—COO—CH2CH2—”,
• “single bond/—OCO—CH2CH2—”, “single bond/—CH2CH2—OCO—”,
• “—OCO—CH2CH2—/single bond”, “—CH2CH2—OCO—/single bond”,
• “—CH2CH2—COO—/single bond”, or “—COO—CH2CH2—/single bond,”
• R1 represents an alkyl group having 1 to 12 carbon atoms, an alkoxy group having 1 to 12 carbon atoms, or “*-Sp-P” (* represents a bond with A4 or A3),
• R3 represents an alkyl group having 1 to 6 carbon atoms, an alicyclic hydrocarbon group, or an aromatic hydrocarbon group, wherein a hydrogen atom in the alicyclic hydrocarbon group or the aromatic hydrocarbon group may be substituted with an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, a halogen atom, a cyano group, a nitro group, a —C≡C—CH3 group, or a hydroxy group,
• m and n each independently represent an integer of 0 to 4 (m+n is an integer of 2 or more),
• T1 represents —S—, —O—, —CH2—, —NH—, —C(═O)—, —S(═O)—, or —C(═S)—,
• T2 represents ═CR2— or ═N—, and
• R2 represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, a cyano group, a nitro group, or a hydroxy group].
