Annual inflation in the euro zone cooled to 0.3% in November, the EU's statistics office Eurostat said today.
Consumer prices were pulled down by falling energy prices and suggesting deflation remains a real threat for the European Central Bank.
The reading was as expected by economists polled by Reuters and followed Germany's inflation reading this week that fell to its lowest level in nearly five years.
The November euro zone figure compared to 0.4% in October.
Inflation has not been at the ECB's target level of close to 2% since the start of 2013 and has been falling since a 3% peak in late 2011.
The ECB considers anything below 1% to be in its deflation "danger zone".
Today's figures show that energy prices fell 2.5% from October and by 1.1% on an annual basis.
Core inflation, stripping out volatile energy and food prices, was 0.7%, unchanged from October but still on a downward trend.
The latest fall in inflation will put pressure on ECB chairman Mario Draghi to take even further steps to revive the economy.
The ECB is due to hold its monthly meeting next week when it could announce measures of quantaitive easing, resulting in a large-scale sovereign bond purchase scheme, a step that has not been taken until now.
"The recovery is still fragile," Valdis Dombrovkis, the European Commission's vice president for the euro and social dialogue, told a press conference.
Also reflecting the general malaise in the euro zone's economy, unemployment remained at 11.5% of the working population for the third month in a row in October.
The number of jobless people actually rose by 60,000 to 18.39 million.
But the unemployment rate was still lower than the 11.9% registered in October last year, according to Eurostat.
Germany registered among the lowest unemployment rates at 4.9% in October, with Spain among the highest at 24%.
In the 28 European Union member states, unemployment stood at 10% in October this year, unchanged from September.
Eurostat estimated that in October 2014, 24.413 million people were unemployed in the 28 member states, including 18.395 million in the euro zone.
That marks an increase of 42,000 in the EU 28, and 60,000 in the euro zone over September 2014.
Compared to October 2013, unemployment fell by 1.549 million people in the EU 28 and by 547,000 in the euro zone.
