Shots were reported from the Nonthaburi branch of the Debsirin School on the outskirts of the capital Bangkok, just after 10:00 local time (03:00 GMT)
Videos from the scene show staff rushing students out of the classroom and police officers trying to find the shooter.
According to the police, he was a 14-year-old student at the school who opened fire on teachers and fellow pupils before taking his own life.
The injured were treated by paramedics before being taken to hospital.
This shooting follows another at a school in southern Thailand in February. That incident raised questions, which will now surely be asked again, about the easy availability of guns in Thailand.
