A plasma processing apparatus includes: a discharge state detecting unit; a history information storing portion; a date-and-time data creating portion; an object specifying data output portion; a data recording portion; and a production history file creating portion. The data recording portion reads out date-and-time data, object specifying data, machine output data representing an operation state of a plasma processing execution portion, and judgment data representing a judgment result of the discharge state, and stores the data in the history information storing portion in time series, each time the plasma processing for the object to be processed is ended. The production history file creating portion that reads out the date-and-time data, the object specifying data, the machine output data, and the judgment result of the discharge state from the history information storing portion based on a designated period or date and time, and creates a production history file.
