Optical component

An optical component comprising:

• a cyclic olefin-based copolymer (A),
• wherein the cyclic olefin-based copolymer (A) has a constitutional unit (a) derived from at least one olefin represented by the following general formula (I),
• a constitutional unit (b) derived from at least one cyclic olefin represented by the following general formula (II), and
• a constitutional unit (c) derived from at least one cyclic olefin represented by the following general formula (III), and
• a content of the constitutional unit (a) is equal to or less than 50 mol % in a case where a total content of the constitutional unit (a), the constitutional unit (b), and the constitutional unit (c) is taken as 100 mol %, and
• wherein a glass transition point (Tg) of the cyclic olefin-based copolymer (A) measured by DSC is equal to or higher than 140° C.,
• in the general formula (I), R300 represents a hydrogen atom or a linear or branched hydrocarbon group having 1 to 29 carbon atoms
• in the general formula (II), R1 to R8 are each independently a hydrogen atom, a halogen atom, or a hydrocarbon group having equal to or less than 4 carbon atoms, R5 to R8 may be bonded to each other to form a monocyclic ring, the monocyclic ring may have a double bond, and R5 and R6 or R7 and R8 may form an alkylidene group
• in the general formula (III), n is 0 or 1, m is 0 or a positive integer, n+m is a positive integer, q is 0 or 1, R1 to R18 and Ra and Rb are each independently a hydrogen atom, a halogen atom, or a hydrocarbon group, R15 to R18 may be bonded to each other to form a monocyclic or polycyclic ring, the monocyclic or polycyclic ring may have a double bond, and R15 and R16 or R17 and R18 may form an alkylidene group.
