The present invention relates to a novel feeder cell and a method for growing gamma delta T cells using the same. More specifically, a large amount of gamma delta T cells may be grown in vitro with high purity and without simulation of a T cell receptor by using a feeder cell into which costimulatory molecules are introduced and a low concentration of IL-2, differentiation into central memory cells may be possible when stimulated, activity by the feeder cell, and cytolytic against tumour cells is provided.
