Lehmann gave a colourful radio interview on the eve of the fifth Ashes Test during which he described Broad's refusal to walk after an edge in the series opener at Trent Bridge as "blatant cheating".
Lehmann also called on the Australian public to "get stuck into him" when England tour this winter, adding that he hoped the seamer "cries and goes home".
Lehmann was found to have breached Article 2.1.7 of the ICC Code of Conduct for Players and Player Support Personnel, which relates to public criticism of, or inappropriate comment in relation to an incident occurring in an International Match or any Player, Player Support Personnel, Match official or team participating in any International Match.
The charge was laid by ICC Chief Executive David Richardson.
Mr Richardson said: “Whilst noting the context and nature of the comments made, showing mutual respect for one’s fellow professionals - including for coaches, players and match officials - is a cornerstone of how we play the game.”
