The invention discloses an ultra-low carbon steel coil plate for an ultra-thin shell of an oil filter and a manufacturing method thereof. The ultra-low carbon steel coil plate comprises the followingchemical components according to the weight percentage: 0.0028 to 0.0050% of C, less than or equal to 0.030% of Si, 0.45 to 0.55% of Mn, less than or equal to 0.012% of P, less than or equal to 0.008%of S, 0. 045-0.080% of Al, 0.065-0.085% of Ti, and less than or equal to 0.0030% of N. The manufacturing method comprises the following steps of: heating a plate blank, and carrying out rough rollingand finish rolling to obtain a hot rolled plate, wherein the coiling temperature is 590-630 DEG C; and carrying out cold rolling on the hot rolled plate to obtain the ultra-low carbon steel coil plate with the thickness of 0.30 to 0.44 mm, wherein the reduction ratio of cold rolling is 80 to 90%, the annealing temperature is 700 to 760 DEG C, the elongation of temper rolling is 1.0 to 2.0% , andthe elongation of straightening and withdrawal is 0.03 to 0.10%. The ultra-low carbon steel coil plate has the Rel of 220-270MPa, Rm of 330-390MPa, hardness of 54-60HR30T, and elongation A80 of greater than or equal to 40%. The ultra-low carbon steel coil plate has relatively high hardness, relatively good ductility, uniform structure property, good isotropic homogeneity and good deep-drawing property, does not generate earing, can completely replace the traditional 0.50-0.70mm thick material, and meets the requirements on thinning and weight reduction of automotive parts.
