Abstract: Provided is a thin-wall article formed from a polyamide resin which can be stably produced with little variation in mechanical properties such as flexural strength, flexural modulus and impact resistance. A thin-wall article formed by molding a polyamide resin (C) obtained by polycondensing a diamine (A) and a dicarboxylic acid (B) or a polyamide resin composition containing the polyamide resin, wherein 70 mol % or more of a diamine structural unit is derived from xylylenediamine and the polyamide resin has a melt viscosity (i) of 50 to 200 Pa·s as measured at a temperature of the melting point plus 10° C. for a holding time of 6 minutes at a shear rate of 122 sec?1.
