The invention relates to an antibody-medicine conjugate targeting an EGFR. The antibody-medicine conjugate targeting the EGFR is characterized in that the antibody-medicine conjugate of a structure shown in a formula I or pharmaceutically-accepted salt or solvate is involved. According to a structural formula of the antibody-medicine conjugate targeting the EGFR, n represents the medicine-antibody proportion and is 3-5; R is O or CONH or NHCO; R is in para-position or meta-position; p is 1-6; m is 0-20. According to the antibody-medicine conjugate targeting the EGFR, based on a bis-ethylene sulfamide connection connexin technology, the antibody-medicine conjugate targeting the EGFR is synthesized for the first time. According to the antibody-medicine conjugate targeting the EGFR, internal sulphur-sulphur bonds of an antibody are broken and then bridged, the conjugate with good uniformity and DAR of about 4 can be obtained, and the antibody is wide in application range.
