PROBLEM TO BE SOLVED: To provide an electroconductivity adjusting material which easily adjusts the electroconductivity of polymer materials to a desired state. SOLUTION: An electroconductivity adjusting material for polymer materials, which is for adjusting the electroconductivity of polymer materials, contains a first fiber group comprising a first carbon short fiber and a second fiber group comprising a first carbon short fiber which has a smaller average fiber size compared with the first carbon short fiber. The first fiber group has a smaller fiber group electroresistance value compared with the second fiber group.
