To provide a measuring method of viscosity of a protein solution capable of being measured with a small amount of sample.SOLUTION: An apparent particle size or apparent molecular weight is measured by an X-ray small angle scattering method (SAXS) or X-ray solution scattering method allowing measurement with a small amount of sample. The viscosity of a protein solution is estimated by correlating the measurement result with the viscosity of the protein solution.SELECTED DRAWING: Figure 1 【課題】少量の試料で測定可能な蛋白質溶液の粘度の測定方法を提供する。【解決手段】少量の試料で測定可能なX線小角散乱法（SAXS）またはX線溶液散乱法により見かけの粒子サイズまたは見かけの分子量を測定し、その測定結果を蛋白質溶液の粘度と相関づけることによって、蛋白質溶液の粘度を推定する。【選択図】図１
