The man pulled alive after 13 days from the devastation of the Iranian earthquake has died of heart failure.
The man gave his name as Jalil before slipping into a coma
Doctors had warned that Jalil Shahiki had little chance of survival when he slipped into a deep coma after his remarkable rescue on Wednesday night.
He survived because he was shielded by a wardrobe under the rubble of the building, and had a supply of water.
More than 30,000 people were killed in the 26 December earthquake which flattened the ancient city of Bam.
One of the medical team treating Mr Shahiki said his death had been caused by heart failure as well as respiratory and pulmonary problems.
Medical officials said the man had only been able to speak his first name, before losing consciousness four days ago.
He had come from his home town of Narmanshir, about 50 kilometres from Bam, the day before the earthquake for medical treatment and was staying with his sister when the earthquake struck.
On 3 January, a woman aged 97 was pulled from the rubble alive and unscathed eight days after the quake.
Survivors have been sleeping in the open in freezing temperatures. With few sanitation facilities, the risk of disease is high.
