    摘要: In at least one of principal surfaces of the electrolyte sheet for a solid oxide fuel cell of the present invention, (1) a burr height [”H (0-3)] in a first zone is 100 µm or less, as measured by irradiating the principal surface of the sheet with a laser beam at a pitch of 0.01 mm using a laser optical three-dimensional shape measurement device, the first zone being a zone extending between a peripheral edge of the sheet and a position 3 mm inside the peripheral edge, and (2) a ratio [”H (0.61-3) / ”H (0-0.6)] of a burr height [”H (0.61-3)] in a third zone to a burr height [”H (0-0.6)] in a second zone is 0.5 or more and 2.0 or less, as calculated from the burr heights measured by irradiating the principal surface of the sheet with a laser beam at a pitch of 0.01 mm using the laser optical three-dimensional shape measurement device, the second zone being a zone extending between the peripheral edge of the sheet and a position 0.6 mm inside the peripheral edge, and the third zone being a zone extending between a position 0.61 mm inside the peripheral edge of the sheet and the position 3 mm inside the peripheral edge.
