PROBLEM TO BE SOLVED: To provide a focusing device of a linear light condensing-type heater in which adjustment of position shift of a heat source lamp inevitably occurring in lamp exchange or the like, or of shift between the focus or the light condensing position from the lamp center and the focus or the light condensing position on a design, which is generated by the manufacturing tolerance and which can not be evaded on manufacturing of the lamp can be carried out very easily. SOLUTION: This is the focusing device of a linear light condensing-type heater in which the cross-section is composed of a linear light condensing-type mirror main body having a reverse U-shaped reflecting face, the heat source lamp arranged in the mirror main body, and an adjusting means installed at both ends of the longitudinal direction of the mirror main body, and in this adjusting means, the center of the heat source lamp moves up and down in the direction for approaching the focus or the light condensing position, or in the direction of separating from the focus or the light condensing position on the design.
