To provide a slip-preventing floor material having an uneven pattern on the surface without using an embossing roller which itself is expensive and which requires additional devices.

The polyvinyl chloride-based slip-preventing floor material is produced by forming an uneven pattern layer 1 of a polyvinyl chloride with a polyvinyl chloride compound having a prescribed composition so that the height of a protruded part may be 0.4 mm thickness measured from the surface on which the uneven part is formed, forming a polyvinyl chloride layer 3 with a polyvinyl chloride compound having a prescribed composition, forming a polyvinyl chloride intermediate layer 4 with a polyvinyl chloride compound having a prescribed composition, and integrating the whole layers with a base material 5.
