Beschreibung
Zusammenfassung:	A cyclic olefin polymer composition comprising: [A] a specific cyclic olefin polymer having a softening temperature (TMA) of 120 to 300° C.; and [B] a specific cyclic olefin polymer having a glass transition temperature (Tg) of 50° C. or lower, wherein the absolute value of the difference between nD[A] and nD[B] is 0.014 or less in which nD[B] represents a refractive index of the cyclic olefin polymer [B] and nD[A] represent that of the cyclic olefin polymer [A], and the component [A] is contained in an amount of 50 to 95 parts by weight and the component [B] is contained in an amount of 5 to 50 parts by weight (provided that the total amount of the components [A] and [B] is defined as 100 parts by weight).
