The present invention provides: an anticancer drug having, as an active ingredient, a bispecific antibody that contains, in a domain including an antibody variable region that binds to glypican-3 and a domain including an antibody variable region that binds to a T-cell receptor complex, a common L chain capable of improving affinity for both antigens and a pharmaceutical composition that includes the bispecific antibody as an active ingredient and that is for concomitant use with another anticancer drug. The bispecific antibody is a novel and highly-safe molecule having high production efficiency, as well as strong antitumor activity and excellent pharmacokinetics, which is expected to be applied to various cancers.
