Zusammenfassung:The present invention provides: an antibody that specifically binds to CD37-positive tumor cells such as B-cell malignant lymphoma; an antibody-drug conjugate that contains said antibody; a pharmaceutical composition that employs said antibody and that exhibits a therapeutic effect on a tumor; a tumor treatment method employing said pharmaceutical composition; a method for producing said antibody; a method for producing said antibody-drug conjugate; and so forth. Provided is an anti-CD37 antibody-drug conjugate in which a drug linker, which is represented by the formula below, and an antibody are bonded by means of a thioether bond (in the formula, A indicates the position at which the linker is bonded with the antibody). Specifically, provided are: a humanized anti-CD37 antibody that exhibits an internalization activity; and an antibody-drug conjugate that contains said antibody.
