摘要： The purpose of the present invention is to provide a synthetic resin-made multilayer bottle such that dead space can be reduced without being affected by the specifications of an outer opening part. The synthetic resin-made multilayer bottle 1 is provided with: an outer shell bottle 2 having a shoulder section 5 continuing from an outer opening part 4 and a body section 6 continuing from the shoulder section 5; a synthetic resin-made inner container body 3 having a cylindrical inner opening part 17 disposed inside the outer opening part 4 of the outer shell bottle 2 and an inner container body 18 having a shape continuing from the inner opening part 17 and matching the shape of the inner surface of the outer shell bottle 2, said inner container body 18 being deformable by external pressure; and an air passage 23 formed between the outer opening part 4 and the inner opening part 17 and introducing outer air between the outer shell bottle 2 and the inner container body 3. The inner peripheral surface of the inner opening part 17 has a small-diameter part 24 having a diameter smaller than the internal diameter of the open end of the inner opening part 17.
