    摘要: The present invention pertains to a resin formed article obtained by forming a resin composition that comprises a cycloolefin resin and a styrene-based thermoplastic elastomer, the styrene-based thermoplastic elastomer having a weight average molecular weight of 20,000 to 150,000, and having a difference in refractive index (ΔnD) of more than -0.002 to less than +0.002 with respect to the cycloolefin resin, the resin composition having a residual ratio of 0.10 wt% or less when analyzed based on the residue on ignition test method specified in the Japanese Pharmacopeia, the resin composition having a light transmittance (optical path length: 3 mm) of 55% or more with respect to light having a wavelength of 450 nm when the resin composition is formed in a shape of a sheet having a thickness of 3.0 mm, and subjected to light transmittance measurement, and the resin composition having a Charpy impact strength of 5 to 40 kJ/m 2 when the resin composition is formed to have a thickness of 4.0 mm, a length of 80.0 mm, and a width of 10.0 mm, and subjected to the notched Charpy impact test specified in JIS K 7111-1 at 23°C.
