The German Federal Statistical office (Destatis) said Friday Germany's annual inflation rate eased to 2.3 percent in May from 2.4 percent in April.
On a monthly basis, the inflation rate in May remained unchanged.
The main contributors were energy and goods prices, which increased 9.5 percent and 3.3 percent respectively, Destatis said.
The European Central Bank (ECB) expressed its concern over high inflation in euro area on Thursday, when announcing its decision to keep its key interest rate at 1.25 percent.
ECB president Jean-Claude Trichet said the inflation rate for euro area in May reached 2.7 percent, mainly driven by energy and commodity prices.
He expected this high level to continue in future months and there were risks inflation remained on the upward trend over the medium term.
But Trichet also stressed his determination to control the inflation, saying: "We will do all that is needed to prevent recent price developments." He also hinted the ECB would raise the key interest rate next month to counter inflation.
