Summary:PROBLEM TO BE SOLVED: To provide a mixture of high specific gravity masterbatch pellets and low specific gravity masterbatch pellets, capable of giving a uniform molded product without causing compositional unevenness. SOLUTION: This mixture of the masterbatch pellet comprises a high specific gravity masterbatch pellet group (A) having a specific gravity of 1.8-3.5 and a low specific gravity masterbatch pellet group (B) having a specific gravity of 0.5-1.6, wherein the high specific gravity masterbatch pellet group (A) is composed of m kinds of pillar-shaped masterbatch pellets of a first kind to an m-th kind so that specific gravities of the m kinds of the pellets are different from each other, the low specific gravity masterbatch pellet group (B) is composed of n kinds of pillar-shaped masterbatch pellets of a first kind to an n-th kind so that specific gravities of the n kinds of pellets are different from each other, and the high specific gravity masterbatch pellet group (A) and the low specific gravity masterbatch pellet group (B) together satisfy formula (1).
