PROBLEM TO BE SOLVED: To provide an injection-molded article which is obtained from a molding composition with the improved moldability, is visually transparent, and is improved in the toughness and the stress-cracking resistance. SOLUTION: This injection-molded article is manufactured from a copolyester that has an acid component comprising the repeating units of 83-52 mol% of terephthalic acid and 17-48 mol% of one or more kinds of additional dibasic acids selected from the group consisting of isophthalic acid and naphthalene dicarboxylic acid, and has a glycol component comprising the repeating units of 70-100 mol% of 1,4-cyclohexane dimethanol and that has an inherent viscosity measured in a 60/40 phenol/tetrachloroethane solution, 100 ml of which contains 0.5 g of the polymer, of 0.4-1.1 dL/g, and the article has a diffused transmission value, according to the method ASTM D1003, of less than 60%.
