The country's strong growth is another sign that the eurozone may have inched out of recession after six quarters of falling output.
Growth was spurred mainly by domestic demand, with the quarter-on-quarter increase in exports larger than the rise in imports, the statistics office said.
Just across the border, the French economy is officially out of recession with its strongest quarterly growth in two years, France's National Statistics Agency said on Wednesday.
Confidence has also recovered as stock and bond markets have rallied. That's partly due to the European Central Bank's pledge a year ago to do "whatever it takes" to save the currency union and its decision to cut its main interest rate to a record low of 0.5 per cent.
In Spain and Italy, for example, government borrowing rates have sunk in the past year, a sign of investor confidence.
