A spread mat capable of reducing, by suppressing slippage, the risk of getting injured by falling even if a surface layer is wet with oil or water. A crushed particulate material of 15 to 80 meshes is sprayed and adhered onto the front surface of the spread mat formed by stacking a large number of synthetic resin filaments in loop shape through an adhesive agent at a distribution rate of 50 to 150 g/m2.
