摘要 |
Provided are a thermoplastic resin shaped-article in which vacancies with satisfactory light emission efficiency are formed, and a thermoplastic resin light guide that uses the thermoplastic resin shaped-article.;Pulse laser irradiation is performed in a state in which the pulse laser is focused to an inner region of a primary thermoplastic resin shaped-article, thereby forming cracks at the inner side of the primary thermoplastic resin shaped-article. Then, a heat treatment is performed at a temperature equal to or higher than a glass transition temperature of a thermoplastic resin that constitutes the primary thermoplastic resin shaped-article, thereby obtaining a thermoplastic resin shaped-article 20 in which substantially spherical vacancies 244 having minimum diameter of 30 μm or more are formed only at the inner region distant from a surface thereof by 10 μm or more. |
