PROBLEM TO BE SOLVED: To provide a resin structure for a mirror frame which has excellent circularity, mechanical strength, and low environmental load. SOLUTION: The resin structure for the mirror frame is obtained by molding a composite resin composition made of a resin containing a cellulose nanofiber having an aspect ratio of 10-1,000,000 and an average diameter of 1-800 nm. The resin structure for the mirror frame is preferably used for a camera. Furthermore, the resin structure for the mirror frame preferably has a difference in mold shrinkage ratio between a vertical and horizontal direction of 0.5% or less. COPYRIGHT: (C)2011,JPO&INPIT
