The object of the present invention is to enable the optical axis of an electron beam of a field emission electron gun mounting thereon an electron gun composed of a fibrous carbon material to be adjusted easily. Moreover, it is also to obtain an electron beam whose energy spread is narrower than that of the electron gun. Further, it is also to provide a high resolution electron beam applied device mounting thereon the field emission electron gun. The means for achieving the objects of the present invention is in that the fibrous carbon material is coated with a material having a band gap, in the field emission electron gun including an electron source composed of a fibrous carbon material and an electrically conductive base material for supporting the fibrous carbon material, an extractor for field-emitting electrons, and an accelerator for accelerating the electrons. Moreover, it is also to apply the field emission electron gun to various kinds of electron beam applied devices.

The present invention has an object to provide a cold cathode field-emission electron gun with low aberration, to thereby provide a high-brightness electron gun even in the case of a large current. The present invention provides a field-emission electron gun which extracts an electron beam from a cathode and converges the extracted electron beam, the field-emission electron gun including: a magnetic field lens which is provided such that the cathode is disposed inside of a magnetic field of the lens; and an extraction electrode for extracting electrons from the cathode, the extraction electrode being formed into a cylindrical shape without an aperture structure. The present invention can provide an electron gun having a function of converging an electron beam using a magnetic field, the electron gun which is capable of reducing an incidental electrostatic lens action and has small aberration and high brightness.

An ink jet recording head includes a substrate having an element surface provided with energy generating elements, a ceiling plate provided with a grooved surface having grooves to become ink passages, the grooved surface and the element surface being bonded to form the ink passages, a base plate for supporting the substrate from the side opposite the element surface, and an ink supply member in contact with the base plate at a contact portion and having an ink flow path wall face to be communicated with the ink passage. The base plate and the ink supply member pinch the substrate and the ceiling plate at the contact portion as a fulcrum so as to enable the base plate to press the substrate from the side opposite the element surface, and the ink supply member to press the ceiling plate from the side opposite the grooved surface.
