The present invention provides anticancer agents comprising as an active ingredient a bispecific antibody that comprises a domain comprising a glypican 3-binding antibody variable region, a domain comprising a T cell receptor complex-binding antibody variable region, and common L chains that can enhance the affinity for the two antigens, as well as pharmaceutical compositions comprising the bispecific antibody as an active ingredient, the compositions being for use in combination with other anticancer agents. The bispecific antibodies are novel molecules which are produced with high efficiency and have strong anti-tumor activity as well as safety and excellent pharmacodynamics. The bispecific antibodies can be expected to be applied to various cancers.
