A novel synthetic resin container includes an entirely or partly dome-like shoulder portion interconnecting a mouth portion and an upper end of a body portion, and provides high strength at the shoulder portion and excellent aesthetic appearance. The shoulder portion has a dome-like region with a plurality of rhombic and triangular bulging portions arranged in the circumferential direction, each protruding outward from its rhombic or triangular outer edge toward its inner edge. The plurality of triangular bulging portions are arranged between the rhombic portions. The rhombic inner edge defines a region protruding inward of the container and thereby forming a rhombic depression, which is provided with a rib having a vertical contour line that protrudes outward. The triangular inner edge defines a region protruding inward of the container so as to form a triangular depression, which is provided with a rib having a vertical contour line that protrudes outward.
