Abstract
Disclosed is a liquid-sealed cartridge in which a liquid is transferred by a centrifugal force generated when the liquid-sealed cartridge is rotated around a rotation shaft, including: a liquid storage portion configured to store the liquid therein; a seal having an outer peripheral portion connected to the liquid storage portion, the seal being configured to seal the liquid storage portion; a flow path connected to the liquid storage portion via the seal, through which the liquid in the liquid storage portion is transferred by the centrifugal force in a direction away from the rotation shaft, wherein, when the seal receives a pressing force, the seal is inclined in a pressing direction, with one portion of the outer peripheral portion thereof remaining connected with the liquid storage portion, and the other portion of the outer peripheral portion being separated from the liquid storage portion.
