A gas discharge panel capable of high-speed driving at a low drive voltage, while suppressing the occurrence of write errors in a write period, and a manufacturing method for the same. To achieve this, in the gas discharge panel of the present invention, a secondary gas formed from at least one of carbon dioxide, water vapor, oxygen and nitrogen is induced into discharge spacesevacuated until the residual gas pressure is 0.02 mPa or less, and an He&#x2014;Xe or Ne&#x2014;Xe rare gas (discharge gas) is induced into discharge spaces. The amount of the secondary gas included within discharge spaceswhen, for example, carbon dioxide is included therein, is suitably set in terms of both a discharge starting voltage and an electron emission ability, so that the partial pressure of the carbon dioxide is in a range of 0.05 mPa to 0.5 mPa inclusive.

In the method of calculating the impedance of an electromagnetic part, the cost is low, the calculation time is short, and data for analysis are easy to handle. In order to allow an axially symmetric three-dimensional magnetic field analysis method to be applied, two kinds of modeling are conducted in a first step on the electromagnetic part; data indicative of the material properties, and various condition data such as an AC voltage to be applied to a winding, and predetermined boundary conditions are prepared in a second step; in a third step, each of two kinds of models is subjected to a coupled analysis of an axially symmetric magnetic field analysis and an electric circuit analysis, a current I flowing through a circuit in response to an application of a voltage E is obtained, and the impedance of each circuit is obtained in accordance with expression 1; and, in a fourth step, a corrected impedance of the electromagnetic part is calculated from the impedances of the models in accordance with expression 3.
