PURPOSE:To obtain the titled carrier with the strain being prevented, by placing on a substrate an ultraviolet-curing resin having a specified viscosity value in the shape of a semisphere, bringing a stamper into contact with the resin under pressure to mold it under pressure, and irradiating it with ultraviolet rays to harden the resin. CONSTITUTION:The disc substrate 4 of an ultraviolet-permeable material (e.g. polyvinyl chloride) is placed on a bottom force 5 of an ultraviolet-permeable meterial, and the ultraviolet-curing type resin 3 having a viscosity of 100-700c. P. is dropped by a dispenser 7 on the center of the surface of the base material. Thereafter, the tip of the dispenser 7 is withdrawn quickly outside of the pressing section, and the stamper 2 of the top force 1 is lowered. The stamper 2 comes in contact with the semisphere-shaped resin 3 at a point, and a pressure of 5-50kg/cm<2> is applied to press and mold it in an annular shape. The resin 3 is finally brought to 1/20 times, preferably, 1/60 times or less as thick as the substrate 4. Ultraviolet rays are irradiated from an ultraviolet light source 6 to cure the resin and to mold signals. |
