A copy of Steve Jobs' death certificate indicates the Apple co-founder died of respiratory arrest that resulted from pancreatic cancer that had spread to other organs.
Jobs died last Wednesday at age 56. Apple Inc. didn't disclose the cause of death, but Jobs had battled pancreatic cancer and had a liver transplant in 2009.
He resigned as Apple's CEO in August while out on his third medical leave in several years.
The death certificate, released Monday by the Santa Clara County Public Health Department, says Jobs died at his home in Palo Alto. No autopsy was performed.
Jobs died the day after Apple announced its latest iPhone, the iPhone 4S, which will go on sale Friday.
