    摘要： A surface acoustic wave filter element and a method of producing the same. The element is constructed in a manner such that a conductive film, which constitutes a plurality of electrode fingers, a bus bar connecting the electrode fingers in common, an electrode pad connected to the bus bar, etc., is formed on a piezoelectric substrate. When using the surface acoustic wave filter element with this arrangement in a high-frequency band, the thickness of the conductive film and the line width of electrodes are reduced, so that the mechanical strength is a critical problem. According to the present invention, therefore, the conductive film has a two-layer structure, including a layer containing tantalum and aluminum and a metallic layer of aluminum or an alloy consisting mainly of aluminum formed thereon, for example. The composition ratio between tantalum and aluminum is set so that the tantalum content ranges from 39% to 75% (atomic percentage). Thus, the orientation the layer of aluminum or the alloy consisting mainly of aluminum, formed on the layer containing tantalum and aluminum, is improved to increase the strength of the conductive film.

    摘要： According to one embodiment, a radiation detector includes, a substrate, a scintillator layer, a moistureproof body, and an adhesion layer. The substrate comprises a photoelectric conversion element. The scintillator layer is formed on the substrate and converts radiation into fluorescence. The moistureproof body comprises a flange portion in a periphery thereof, the moistureproof body being deep enough to contain at least the scintillator layer. The adhesion layer causes the substrate and the flange portion of the moistureproof body to adhere to each other in a sealed manner.

    摘要： In a radiation detector in which scintillator layers are directly formed on all the light receiving parts of a plurality of photoelectric conversion substrates, space and level difference between the adjacent photoelectric conversion substrates are determined so that the effects of these space and level difference fall within a range corresponding to the effect of one photoelectric conversion element. Specifically, the space between the adjacent photoelectric conversion substrates is equal to or less than 133 μm and the level difference between the adjacent photoelectric conversion substrates is equal to or less than 100 μm. Accordingly, the scintillator layers can be directly formed on all the light receiving parts of the plurality of photoelectric conversion substrates. This prevents degradation in MTF and sensitivity and reduces manufacturing costs.
