Abstract: A sensor according to a first embodiment of the present invention includes a flow channel to permit passage of a specimen, a first detection part that is located in the flow channel and has a first ligand specifically bindable to a first material in the specimen, and a second detection part that is located downstream of the first detection part in the flow channel and has a second ligand specifically bindable to the first material and/or a second material in the specimen.

Abstract: An acoustic wave device and an electronic component are disclosed. The acoustic wave device includes a substrate, excitation electrodes on the substrate and a cover. The cover comprises a frame member on the substrate, and a lid member. The frame member surrounds the excitation electrodes and includes an inner wall, top surface and an outer wall.

Abstract: A sensor which uses a detection element such as a surface acoustic wave element, and includes a flow passage for a specimen is provided. A sensor includes a substrate; a detection element located on the substrate and having a detection portion which detects an object to be detected contained in a specimen, in an upper surface thereof; and a flow passage structure located on the substrate and covering the detection portion with a space. The flow passage structure has an inlet for the specimen, a flow passage continuing from the inlet, and a space which continues from an end portion of the flow passage closer to the detection element and is located above the detection portion, and a bottom surface of the flow passage has, on the end portion of the flow passage closer to the detection element, a notched portion whose width gradually decreases toward an upstream of the flow passage.
