Abstract: Provided is a substance capable of effectively suppressing cancer metastasis or a pharmaceutical composition that effectively acts on an inflammatory disease. The pharmaceutical composition is a pharmaceutical composition containing, as an active ingredient, an antibody or an antibody fragment thereof having antigen-binding activity for an S100A8/A9 heterodimer, and blocks interaction between S100A8/A9 and a group of receptors therefor, to thereby strongly suppress cancer metastasis both in vitro and in vivo, or alleviate inflammation. That is, the anti-S100A8/A9 antibody or the antibody fragment thereof can strongly suppress cancer metastasis or alleviate inflammation, by virtue of its blocking action on the interaction between S100A8/A9 and the group of receptors therefor.
