The baby boy survived the fall but is in a 'serious condition' and is suffering from hypothermia, Sky News reported.
According to local police, although the baby was not breathing and his heart had stopped beating, doctors have managed to revive him.
Police has taken the 35-year-old mother into custody on suspicion of attempting to kill the baby.
Police said in a statement that they found the baby wrapped in a pair of jeans.
The woman, who lived with her parents in eastern Madrid, delivered the baby by cutting the umbilical cord herself, and throwing the baby out of the window.
