PROBLEM TO BE SOLVED: To obtain a molding product and a lamp extension part, hardly causing shrinkage when exposed under high temperature conditions, having high load deflection temperature and small thermal expansion and warping and excellent in surface appearance. SOLUTION: This molding product is obtained by molding a resin composition comprising (A) 100 pts.wt. thermoplastic polyester and (B) 50-150 pts.wt. amorphous resin having >=170 deg.C glass transition point. The molding product has 50 deg.C to 150 deg.C half value width of peak of dynamic loss modulus E caused by main disperse relaxation when temperature raising rate is 15 deg.C/min and 160 deg.C to 250 deg.C temperature of maximum value of the loss tangent, tanδ.
