    摘要： The additive (b) for a communication cable filler according to the present invention contains as a main component an ethylene/α-olefin copolymer (a) having a number-average molecular weight (Mn), measured by GPC, of 500 to 5,000 and having a crystallizing temperature (Tc (° C.), rate of temperature decrease: 2° C./min) measured by DSC and a density (D (kg/m3)) measured by a density gradient tube method, said Tc and D satisfy the following formula (1): 0.501×D(kg/m3)−366≧Tc(° C.)  (1). The communication cable filler (c) according to the invention is prepared by blending (X) 40 to 90% by mass of polybutene (d) having a number-average molecular weight of 200 to 2,400, (Y) 1 to 50% by mass of an oil (e) and (Z) 1 to 15% by mass of the ethylene/α-olefin copolymer (a). The additive for a communication cable filler and the communication cable filler are excellent in the filling workability and the oil retention properties of a cable jelly.
