The object of the present invention is to provide a high quality 
polyester resin having 
high productivity, stability and safety, a catalyst for 
polyester production with high catalytic activity, a method for producing the 
polyester resin with the catalyst, a 
polyester resin obtained with the catalyst, and a hollow molded container comprising the 
polyester resin. The 
polyester resin of the present invention satisfies specific parameters regarding polymerizability, stability, and 
metal content. The catalyst for polyester production satisfies specific parameters. The catalyst particularly preferably comprises: (a) a 
solid titanium-containing compound which has a maximum 
solubility in 
ethylene glycol of 1,000 ppm or more in terms of converted 
titanium amount when dissolved in 
ethylene glycol with heating at 150° C., and which comprises 
titanium, 
oxygen, carbon, and 
hydrogen, and optionally 
alkali metal, and has a Ti—O—C bond; and (b) an 
alkali metal compound, the 
molar ratio of the 
alkali metal atoms to the 
titanium atom in the catalyst being in the range of 20 / 1 to 0.1 / 1.
