To obtain the basic information for the effective use of collagen, the flow behavior of collagen extracted from skin tissue was studied. The viscosity of collagen varied with sex, age and the kinds of collagen by extraction method. Regardless of the kinds of collagen, the viscosity of collagen extracted from $6{\sim}12$ week old rat was relatively high. In case of the same age, the viscosity showed higher in female than in male rat and in acid soluble collagen than in insoluble collagen. The solution of the collagen showed the characteristics of Bingham plastic and thixotropic fluid, and the viscosity varied distinctly with temperature, pH, ethanol concentration and collagen concentration. As collagen concentration increased to 6%, the consistency of acid soluble- and insoluble collagen showed a tendency to increase linearly(r = 0.972 for acid soluble collagen, r = 0.957 for insoluble collagen). In that range of collagen concentration, the increasing velocity of consistency was higher in acid soluble collagen than in insoluble collagen. The consistency of collagen solution was decreased according to temperature rising. In case of acid soluble collagen, the consistency is decreased abruptly between $30{\sim}40^{\circ}C$. According to pH variation, the consistency of acid soluble collagen showed biphasic phenomenon, though the consistency of insoluble collagen was found not to be influenced by pH. The consistency of acid soluble- and insoluble collagen according to ethanol concentration showed high between $40{\sim}60%$ of ethanol concentration.
