A manufacturing method of polyvinyl chloride artificial leather of which water absorbing power is improved is provided to offer inexpensive raw material cost compared to manufacturing cost of the existing polyvinyl chloride artificial leather containing silk crushed materials. A manufacturing method of polyvinyl chloride artificial leather of which water absorbing power is improved includes a surface layer(3) containing polyvinyl chloride resin 85 ~ 95 weight%, soybean protein crushed materials 5 ~ 15 weight% of which average diameter is 5 ~ 75 mum, and a coating layer(4) containing the soybean protein crushed materials of which diameter is 5 ~ 75 mum and an adhesive with a weight ratio of 70 : 30 ~ 60 : 40. The polyvinyl chloride artificial leather further includes one or more layer selected from a base layer(1) and a foam layer(2). The degree of polymerization the polyvinyl chloride resin is 900 ~ 1400. The base material layer is one or more selected from cloth, non-woven, and raw cotton etc.
