He said the large number of players of foreign origin in the side was an indication of improving integration in a country of 82 million with a foreign population of about seven million.
"It's tremendous progress - 11 of the 23 Germany players are from immigrant families," De Maiziere, who is also the Interior Minister, told Deutschlandfunk radio.
"They've worked hard, delivered a great performance. They wanted to become German citizens and they've done that without turning their backs on their home countries," he added. "We've accepted that and they're loved as much as anyone else.
"It's a successful example of integration - a role model for our country."
The families of Miroslav Klose and Lukas Podolski came from Poland, Mesut Ozil is of Turkish descent, Sami Khedira's father is from Tunisia, Jerome Boateng's father is Ghanaian and Mario Gomez was born to a Spanish father and German mother.
"This team is a successful example of integration," added de Maiziere. "Those who work hard will be accepted and those who have faith (in Germany) will have opportunities."
