The invention provides an electron emitting element, an electron emitting device, a light emitting device, an image display device, an air blowing device, a cooling device, a charging device, an image forming apparatus, an electron-beam curing device, and a method for producing the electron emitting element. The electron emitting element of the present invention includes an electron acceleration layer between an electrode substrate and a thin-film electrode. The electron acceleration layer includes a binder component in which insulating fine particles and conductive fine particles are dispersed. Therefore, the electron emitting element of the present invention is capable of preventing degradation of the electron acceleration layer and can efficiently and steadily emit electrons not only in vacuum but also under the atmospheric pressure, thereby improving the mechanical strength.
