Abstract
An aluminum alloy support for a planographic printing plate is disclosed, which is an aluminum alloy plate comprising 0<Fe.ltoreq.0.20 wt %, 0.ltoreq.Si.ltoreq.0.13 wt %, Al.gtoreq.99.7 wt % and the balance of inevitable impurity elements, wherein the number of intermetallic compounds present in the arbitrary thickness direction with in 10 .mu.m from the plate surface is from 100 to 3,000 per mm.sup.2 and the intermetallic compound has an average particle size of from 0.5 to 8 .mu.m, with the intermetallic compounds having a particle size of 10 .mu.m or more being in a proportion by number of 2% or less. Also disclosed is a method for producing the above-described aluminum alloy support.
