Herein disclosed are a bottle of a saturated polyester resin and its method of production. According to the method of the present invention, saturated polyester resin is injection-molded into a parison which is composed of a mouth and a barrel. The mouth of the parison is oriented in the direction of the axis of the parison and in a direction perpendicular to the parison's axis by means of an orienting jig. The barrel of the parison is biaxially oriented by a blow-molding process. The bottle thus produced has been oriented as a whole.
