It says that in Spain, 74 percent of those asked said they felt it was "probably true" that Jews hold too much sway over the global financial markets.
Nearly two-thirds of Spanish respondents said Jews were more loyal to Israel than they were to their home countries.
"This poll confirms that anti-Semitism remains alive and well in the minds of many Europeans," said Abraham H. Foxman, the ADL's national director in America. "Clearly, age-old anti-Semitic stereotypes die hard."
Foxman said the study's findings were particularly worrisome in light of the anger spawned by the global economic meltdown, and following a number of violent acts against Jews or Jewish property after Israel's military action in the Gaza Strip.
Around Europe, several attacks have been reported against Jews and synagogues in France, Sweden, and Britain since the Israeli offensive began in late December. Some Gaza protests in Europe have included Nazi imagery, including signs and slogans comparing Israeli soldiers to German troops and the Gaza Strip to the Auschwitz death camp.
Britain consistently registered the lowest levels of anti-Jewish sentiment, and numbers there have fallen from a similar survey conducted in 2007. Austria also registered a slight drop in the level of anti-Semitism, while in other countries anti-Semitic sentiment either remained the same or deepened.
The survey was conducted by First International Resources Dec. 1 through Jan. 13. The margin of error for each country was plus or minus 4 percent.
