A titania porous body is entirely formed of titania. The titania porous body includes a titania framework, first pores, and second pores. The titania framework forms a three-dimensional network structure. The first pores are opening portions of the three-dimensional structure. The second pores are disposed in a surface of the titania framework. Such a titania porous body is also referred to as a titania monolith.

A method of manufacturing a piezoelectric element including a step of preparing a green sheet A including a portion which becomes a fired piezoelectric body later, by use of a piezoelectric material; a step of joining, to at least one surface of the green sheet A, a green sheet B having an opening in a portion facing the portion which becomes the fired piezoelectric body later, followed by firing to obtain the fired piezoelectric body provided with a reinforcing plate to which the reinforcing plate formed owing to the firing of the green sheet B is attached; and a step of forming a film-like electrode in a portion obtained by the firing of the green sheet A in the fired piezoelectric body provided with the reinforcing plate.

Method of manufacturing piezoelectric element

In the manufacture of a laminated piezoelectric/electrostrictive element by lamination of a piezoelectric/electrostrictive film and an electrode film containing either platinum or an alloy composed mainly of platinum and having a thickness of 2.0 &#x3bc;m or less, both or either one of yttrium oxide (YO) and cerium oxide (CeO) is added to the electrode film or the piezoelectric/electrostrictive film, and the electrode film and the piezoelectric/electrostrictive film are fired simultaneously. This simultaneously achieves a reduced thickness and improved thermal resistance of the electrode film and a reduced change in piezoelectric/electrostrictive properties with time, thereby producing a piezoelectric/electrostrictive element with good initial piezoelectric/electrostrictive properties and with a small change in the piezoelectric/electrostrictive properties with time.

A flow passage component according to the present invention is a component composed of ceramics, which forms a flow passage through which a liquid flows. The flow passage has a discharge opening at an end of the flow passage, for discharging the liquid in the flow passage to a space outside of the flow passage component. The discharge opening is exposed to the outside space. A flow passage wall surface forming the flow passage is covered by/with a protection film (parylene-film) formed of a paraxylylene-based polymer. Further, the parylene-film is formed so as to have its end at a position upstream of the discharge opening by a predetermined distance along the flow passage wall surface from the discharge opening. This can decrease a possibility that the liquid goes around the 'outer wall surface on which the discharge opening is formed.'
