The National Disaster Co-ordinating Council (NDCC) said half of those killed were pinned down by fallen trees or hit by flying debris as the storm hit northeastern provinces Pangasinan, La Union and Zambales.
The storm is expected to head towards southern Japan early on Tuesday.
Around 35,000 people were affected by the storm and some areas lost electricity after its strong winds toppled electric posts and tripped power lines.
Homes swamped
Amado Espino, the governor of Pangasinan, said: "It would take at least a month to restore 100 per cent power in my province."
He said about $3.7 million worth of crops such as rice and vegetables were destroyed by floods and hundreds of houses were damaged by strong winds.
In nearby Zambales province, troops were sent to help evacuate hundreds of people from coastal villages after huge waves swept away dozens of houses.
Landslides and floods are common in the Philippines, which faces about 20 typhoons each year.
About 1,200 people were killed when flash floods rampaged through low-lying areas in Legaspi City in the east in 2006.
