PROBLEM TO BE SOLVED: To provide an oil fence which has a float bag hardly punctured, by which oil absorption quantity can be increased, oil leakage can be reduced, it can be less apt to be bulky before use, and further the incineration amount can be decreased by installing a floating bag in a cylindrical bag formed by a lipophilic deformed fibrous cloth, the deformation degree of which is specified. SOLUTION: A floating bag 12 made of polyethylene, which is swollen by injecting gas is installed in a cylindrical bag 11 formed by a lipophilic deformed fibrous cloth, which has the deformation degree expressed by the equation: K=L(4πS)<1/2> ranging from 1.1 to 10. Where, S indicates the sectional area of the fiber forming the cloth, and L indicates the average value of total circumferences of fibers forming the cloth. Further a skirt 13 formed by the same non-woven fabric as that of the cylindrical bag 11 is fitted to the outer peripheral surface of the cylindrical bag 11. Compressed air or the like is injected into the floating bag 12 from a filling port 12a, and when the bag is thrown down on the surface of the sea where oil flows out, an oil absorption type oil fence 10 is floated on the water surface by the floating bag 12 to interrupt outflow of oil and simultaneously absorb oil floating by the cylindrical bag 11 made of lipophilic raw material.
