    • A cyclic olefin resin composition which can be suitably used as a material for a substrate having low permittivity, low dielectric tangent, low water absorbability, excellent heat resistance, and the like, and a substrate obtained from the resin composition are provided. In particular, there is provided a novel cyclic olefin resin composition that can be suitably used as a material for a substrate for high frequency circuit dealing with high frequency signal transmission. The cyclic olefin resin composition comprises (A) 5 to 95 parts by weight of a cyclic olefin polymer having a glass transition temperature of 60 to 200° C. and (B) 5 to 95 parts by weight of a flexible copolymer, prepared by polymerizing at least two monomers selected from the group consisting of an olefin compound, a diene compound and an aromatic vinyl hydrocarbon compound, and having a glass transition temperature of 0° C. or below. The cyclic olefin resin composition further comprises, based on 100 parts by weight of total amount of the components (A) and (B), (D) 0.01 to 5 parts by weight of a radical initiator and (E) 0 to 5 parts by weight of a polyfunctional compound having in its molecule two or more radically polymerizable functional groups.
