Abstract: A measurement system according to an aspect of the present invention enables measurement of an intensity distribution of diffracted X-rays obtained by irradiating a fillet portion of a metallic structure with X-rays, the metallic structure comprising: an axis portion; and a flange portion protruding radially from the axis portion, wherein the metallic structure comprises the fillet portion in a connection portion between the axis portion and the flange portion, the measurement system including: a diffracted X-rays measurement device provided with an irradiation unit that irradiates the fillet portion with X-rays; and a positioning device that positions the diffracted X-rays measurement device with respect to the fillet portion, in which the positioning device including: a moving mechanism that moves three-dimensionally the diffracted X-rays measurement device relative to the fillet portion; and a rotation mechanism that rotates the diffracted X-rays measurement device in such a direction that an angle of inci

Abstract: An electrolyte sheet including an electrolyte layer that includes electrolyte particles and a binder, and a base material stacked on the electrolyte layer, wherein the electrolyte particles have an ionic conductivity of 1.0×10?5 S/cm or more; the ratio of the electrolyte particles relative to the total weight of the electrolyte particles and the binder is 50 wt % or more and 99.5 wt % or less; and, after transferring the electrolyte layer in a transfer test, the electrolyte particles and the binder do not remain on the base material, and the electrolyte layer is transferred to an object without peeling.
