<p>PROBLEM TO BE SOLVED: To provide a timepiece component excellent in dimension stability and self-tapping property.SOLUTION: Provided is the timepiece component formed of a polyamide resin composition formed of: a crystalline semi-aromatic polyamide(A); a polyamide other than (A)(B); and a fibrous reinforcement material (C). In the polyamide resin composition, a mass ratio:(A)/(B)=100/0-60/40 is satisfied, and a mass ratio:(C)/{(A)+(B)}=10/100-80/100 is also satisfied. The crystalline semi-aromatic polyamide resin (A) is a polyamide 6T, a polyamide 9T, or a polyamide 10T.</p> |
