A method and implementing system are provided in which a user is enabled to view source code within a context of the screen presentation which is created by the source code. The negative electrode has a negative electrode current collector and negative electrode active material layers, formed on respective surfaces of the negative electrode current collector. Since the memory 10 and the drive unit 5 are loaded in the self-emitting module 1, in a state in which the self-emitting module is an individual module body before the module 1 is connected with a main body substrate 6 side, intensity adjustment of the respective light emitting elements can be performed, and adjustment work for intensity prior to shipping of the product can be made easier. The volatilized material may contain a volatilized solute and vehicle such that the resulting aerosol particle sizes of the solute and the vehicle are either different or the same.
