An object of the present invention is to provide a bispecific antibody, which binds to CD40 and FAP and exhibits a strong CD40 agonistic activity in a FAP dependent manner or a bispecific antibody fragment thereof, and the like. The present invention relates to a bispecific antibody, which is a bispecific antibody containing an IgG portion including a first antigen binding domain and also containing a second antigen binding domain, and binding to human CD40 and human FAP, wherein the C terminus of a heavy chain of the IgG portion binds to the second antigen binding domain either directly or via a linker, or a bispecific antibody fragment thereof, and the like.
