PROBLEM TO BE SOLVED: To provide a single-layer cylindrical solid synthetic resin container with printed braille that can be read easily by touching, and a manufacturing method for the solid synthetic resin container. SOLUTION: Braille ink is made by blending together liquid or gel epoxy colored ink, a solvent reducing the viscosity of the colored ink, a gel extender 20% in volume of the colored ink, a granular or powdered resin 20% in volume of the colored ink, and a liquid hardener 10% in volume of the colored ink. The braille ink is printed on the curved side face of the solid synthetic resin container 16 on rotation through braille pattern holes having diameters of 1.2 mm to 1.5 mm that penetrate a fluorine-coated silk screen impregnating emulsion layer having 60 to 90 meshes per square centimeter and a layer thickness of 500 to 800μm. The braille ink is dried and hardened in an atmosphere of 100 to 120°C for 5 to 15 minutes in a drying furnace to expose a printed braille portion 14 of a cylindrical single layer on the curved side face of the solid synthetic resin container 16.
