Abstract: A photocurable composition for three-dimensional modeling capable of high-speed modeling, a three-dimensional modeled object using the composition, and a method for producing the three-dimensional modeled object is provided. A photocurable composition for three-dimensional modeling, comprising a polymerizable organic compound component is provided. The photocurable composition has a steady flow viscosity of 30,000 mPa s or less measured with a rotary rheometer at 25° C. and a shear rate of 0.01 per second. When the photocurable composition for three-dimensional modeling is irradiated with a light having a light intensity of 1.3 mW/cm2, G′ becomes 1×106 Pa or more after a start of photopolymerization in an integrated light irradiation time of 4 seconds or less. After the start of photopolymerization, a maximum value of tan δ on and after a gel point is 0.5 or more. The gel point is the point where G′=G″ is satisfied for the first time after the start of photopolymerization. G′ is a storage shear modulus, G′ is loss shear modulus, and tan δ is a loss tangent, each of which is calculated based on measurement data for 30 seconds per one measurement, measured with a rotary rheometer having a pair of parallel plate with a diameter of 10 mm and a measurement gap of 0.1 mm at a strain of 0.5% or less, a frequency of 0.1 Hz, and 25° C.
