The blast occurred during a crowded memorial service in the Farmay Adha area for a former mujahedin commander, Younis Khalis, who died earlier this month.
Provincial Police Chief Abdul Basir Solangi said the bomb was planted in a car used by police officers to drive to the mosque.
Most of the dead are believed to have been either guards or police officers.
The governor of Nangarhar Province, Gul Afgha Sherzai, was in attendance, but escaped unhurt.
He said he had been the target of the attack, which he blamed on the "enemies of Afghanistan," a reference to Taliban insurgents and Al-Qaeda militants.
Meanwhile, Afghan forces reportedly killed 23 Taliban insurgents in raids on two southern Afghan hideouts on July 30. The raids took place near the Helmand provincial town of Garmser, which Taliban forces overran and briefly took control of earlier this month.
