PROBLEM TO BE SOLVED: To provide a resin having excellent heat resistance and transparency and also having excellent scratch resistance, and a composition for producing the resin.SOLUTION: A resin includes a polymer having an adamantane skeleton and an inorganic filler. A first linear expansion coefficient in the range of 20°C-90°C is 40-110 ppm, a second linear expansion coefficient in the range of 180°C-220°C is 40-150 ppm, and the difference between the first linear expansion coefficient and the second linear expansion coefficient is equal to or less than 50 ppm. |
