A solid electrolytic capacitor that includes a laminated body, a solid electrolyte layer, and conductive bases. The laminated body is obtained by laminating a plurality of dielectric-coated valve action metal sheets, each of which includes a valve action metal base and a dielectric coating, and joining together the adjacent valve action metal bases. The valve action metal base has a cathode layer part, and the dielectric coating covers the surface of the valve action metal base at least the cathode layer part. The valve action metal base of at least one of the dielectric-coated valve action metal sheets further has an anode lead part. The solid electrolyte layer is a continuous layer that fills gaps between the dielectric-coated valve action metal sheets and covers the outer surface of the laminated body at the cathode layer parts, and conductive bases are provided in the solid electrolyte layer.

A method for manufacturing a surface acoustic wave apparatus decreases a specific resistance of an electrode film by removing hydrogen occluded in the electrode film that is primarily composed of tantalum, so that the device properties are stabilized. An electrode film primarily composed of tantalum is formed on a piezoelectric substrate. Subsequently, this electrode film is heat-treated in a vacuum at a temperature of about 200° C. to about 700° C. for several hours. Thereafter, the electrode film is patterned so as to produce an interdigital electrode transducer.

A electromagnetic relay in which bad electrical contact and failure of operation are prevented even when shavings are produced while an iron core is press-fitted into and mounted on a base. The electromagnetic relay includes an electromagnetic block supported by press-fitting both ends of an iron core of the electromagnetic block into an upper surface of a base and open or close a contact by a movable iron piece rotated by magnetization or demagnetization of the iron core with a coil, where shaving receptacles are made by forming separating ribs adjacent to at least one side of press-fit projections that are formed in press-fit concave portions provided on the upper surface of the base.

A surface acoustic wave sensor detects a mass load on a resonator-type surface acoustic wave filter on the basis of a change in frequency and includes an IDT electrode arranged on a piezoelectric substrate to excite surface waves, an insulating film arranged so as to cover the IDT electrode, and a reaction film which is disposed on the insulating film and which reacts with a target substance to be detected or a binding substance that binds to a target substance to be detected. The reaction film is composed of a metal or a metal oxide.

In a sensor for detecting a substance in liquid, recesses are provided in the upper surface of a base substrate. The recesses respectively accommodate SAW elements. A resin layer having openings is arranged such that the sensing portions at the upper surfaces of the SAW elements are exposed in the openings. A reaction film made of a material capable of binding to a target substance is also arranged so as to cover the sensing portion of at least one of the SAW elements. A liquid containing a target substance is fed from the openings.
