"This material certainly provides sufficient basis for indictment in a court of law," Riaz Mohammad Khan, a Foreign Ministry spokesman, told journalists in Islamabad.
Pakistan's President, General Pervez Musharraf, has insisted that Pakistan should see proof of Bin Laden's guilt before any military action is taken in Afghanistan.
Afghanistan's ruling Taleban has been sheltering Saudi-born Bin Laden since 1996.
Mr Khan's comments come as UK Prime Minister Tony Blair prepares to visit Pakistan as part of an intensive diplomatic effort to shore up support for military action against the Taleban.
Mr Khan also said the evidence linked Bin Laden to other attacks, although he did not say which ones.
And he declined to say if the evidence provided by the US was strong enough to justify military action against the Taleban and Bin Laden's al Qaeda network.
Washington has consistently refused requests from the Taleban to be shown the evidence against Bin Laden.
Mr Khan said Pakistan would not pass the evidence on to the Taleban.
Intense pressure
Pakistan has long been considered a close ally of the Taleban and is the only government that still recognises its legitimacy.
But it has come under intense pressure from the US to co-operate in its war against global terrorism.
Pakistan, wary that a substantial minority of its citizens support Bin Laden, has given the US military support, but has not agreed to let US troops be stationed on Pakistani territory.
In return, the US has dropped sanctions against Pakistan.
Post-Taleban deals
President Musharraf said on Wednesday that he believed only a broad-based, multi-ethnic government could succeed in Afghanistan if the ruling Taleban authorities were ousted from power.
General Musharraf made the comments during an address to ministers and heads of the armed forces.
The BBC Islamabad correspondent says this sounds similar to the kind of post-Taleban administration being discussed by members of the US-led coalition against terrorism.
Western diplomats have been courting the former Afghan King, Zahir Shah, and the opposition Northern Alliance have indicated they would be ready to work with him.
The 86-year old former monarch, who was deposed in 1973, lives in exile in Rome.
The former king has welcomed General Musharraf's invitation to send a representative to Islamabad for talks.
