RESIN MOLDED BODY, MICROCHIP AND THEIR PRODUCTION METHODS

摘要

Disclosed is a resin molded body which is good in fillability of the resin and releasability of the molded body, while enabling to form micro recesses and projections having a size from hundreds nm to hundreds µm with high precision. This resin molded body is characterized by comprising a micro three-dimensional shape portion having a width A, a height B and a length C, with A being not less than 5 µm and not more than 100 µm, B/A being not less than 1 and not more than 10 and C/A being not less than 0.5 and not more than 1.5. The resin molded body is also characterized in that it is formed by injection molding using a thermoplastic resin having a flexural modulus of not less than 100 MPa and not more than 1500 MPa.
