The imitation playing field was created by using nanotechnology.
It measures 500 by 380 nanometres and can only be seen through a special microscope. A nanometre is a billionth of a metre.
The tiny football field was created by Stefan Trellenkamp, whose country is hosting the 2006 World Cup.
"I am really, really proud," said the nanotechnology researcher from the University of Kaiserslautern.
"The only problem is that I really don't know what to do with it. I can't put it on show as no one can see it," he said.
Maybe a tiny FIFA can take care of it for him.
