Abstract: Provided is a sensor unit including a first sensor portion that detects deformation of a measuring target object and a second sensor portion that detects deformation of the measuring target object, in which in a state in which the first sensor portion and the second sensor portion are attached to the measuring target object, the first sensor portion and the second sensor portion are fixed to the measuring target object such that the measuring target object is disposed between the first sensor portion and the second sensor portion in a first direction, and a physical property value of the first sensor portion and a physical property value of the second sensor portion are changed according to first deformation of the measuring target object.

Abstract: In a flange fastening structure, a turbocharger includes a wastegate decentered from a center of a first flange that surrounds an outlet opening of the turbocharger. A bolt of a V-band that fastens the first flange on the turbocharger to a second flange on an exhaust passage member is disposed in a first region. The first region is a region composed of two sector-shaped regions each having a central angle of 90 degrees from a straight line from the center through a point that is on the first flange and that is closest to a maximum opening portion of the wastegate toward a corresponding side in a circumferential direction.

Abstract: A thermoelectric conversion material (10) according to an embodiment includes a plurality of parent-phase particles (22) and nanoparticles (30). The parent-phase particles (22) have a crystalline structure. Each of the nanoparticles (30) includes an oxide and exists at an interface between the parent-phase particles (22). The nanoparticles (30) include at least one element that constitutes the crystalline structure. When a range of 6 ?m×4 ?m of the thermoelectric conversion material (10) is observed with a scanning electron microscope to acquire one sheet of cross-sectional observation image, an average particle diameter d, which is an average of an equivalent circle diameter of a particle group including the parent-phase particles (22) and the nanoparticles (30) which are observed on the cross-sectional observation image, is equal to or more than 100 nm and equal to or less than 1000 nm.
