The invention discloses an electrogalvanized ultra-deep-drawn steel plate with a high-roughness surface. The electrogalvanized ultra-deep-drawn steel plate comprises the following components in percentage by weight: C not more than 0.0018%, Si not more than 0.015%, 0.05-0.18% of Mn, P not more than 0.015%, S not more than 0.010%, 0.03-0.05% of Nb, 0.02-0.05% of Als, N not more than 0.003%. A production method comprises the steps of smelting, blank casting, hot rolling and cold rolling, continuous annealing, leveling, cleaning by alkali washing, brushing, electrolytic degreasing and rinsing procedures, electrogalvanizing by a gravity method, and standby. Under the precondition of guaranteeing soft steel use mechanical performance and excellent tensile property, in a direction perpendicular to a rolling direction, the yield strength is 110-170 MPa, the tensile strength is 260-330 MPa, the plastic strain ratio r90 is not lower than 2.5, the machining hardening index n90 is not lower than 0.22, and the ductility A80mm is not lower than 43%; the surface roughness Ra of the steel plate is not lower than 0.9 micron; and a plating layer is strong in bonding force.
