PROBLEM TO BE SOLVED: To enhance physical properties such as a strength of a carbon fiber-reinforced polyolefin resin. SOLUTION: In a carbon long fiber-reinforced resin pellet, a carbon long fiber (B), which is subjected to surface treatment by using a sizing agent (s) with a functional group capable of reacting with an acid group, is impregnated with a polyolefin resin (A) containing the acid group, wherein an acid amount is in a range of 0.05-0.5 wt% on an average in terms of maleic anhydride, in such a manner that a weight ratio of the fiber (B) to the total weight of the resin (A) and the fiber (B) is in the range of≥5 wt% and <50 wt%. The carbon fibers are arranged with the same length in parallel in the length direction of the pellet, and the length of the carbon fiber is set to be in the range of 4-50 mm.
