The present invention addresses the problem of evaluating the hydrophobicity of a powder. According to the present invention, a powder is charged into a mixed solvent composed of a lipophilic solvent and a hydrophilic solvent, the voltage rate R of the mixed solvent is measured at predetermined time intervals while adding a lipophilic solvent to the mixed solvent charged with the powder, a parameter x correlating with the concentration of powder is defined for an arbitrary voltage rate R, a continuous function HP(x) of the ratio of a lipophilic solvent corresponding to x is defined, and HP(x) for required x is set as a representative value of a lipophilic solvent ratio distribution and used as an index of hydrophobicity.
