A strip brush seal device for improving a seal capability of a seal portion, promoting an elastic deformation of the seal portion, and preventing wear of the seal portion. Also for providing a secure joint to a mounting portion of the strip seal brush. The strip brush seal comprises a mounting portion which is located toward the side of protrusions of individual seal strips in which the protrusions of the seal strips are integrally joined along a direction of width of the strip, a strip brush seal which retains a seal portion to the radially inward direction relative to the mounting portion, a back plate which is disposed in the opposite side of the action of a process fluid, and a joint portion which is formed by welding the individual protrusions of the seal strips.
