The invention provides a plasma processing apparatus and a control method, for monitoring distribution of plasmas. The plasma processing apparatus includes: a plurality of gas supply nozzles which areprovided on a wall surface of a processing container and supply process gas toward the inside of the processing container in a radial direction; N microwave introducing modules of which the number disposed in a circumferential direction of a ceiling plate of the processing container so as to introduce microwaves for generating plasma into the processing container; and sensors, wherein N or multiple of N sensors are arranged on the wall surface of the processing container so as to monitor at least any one of electron density Ne and electron temperature Te of the plasma generated in the processing container; and N>=2.
