PURPOSE:To provide a manufacture and manufacturing device of a heat insulating panel where it can spread a mineral fiber uniformly between metallic hoop materials and is free from scattering also to the circumference. CONSTITUTION:A mineral fiber 3 is spread by a spreader 5 which reciprocates in the direction meeting at right angles with a conveying direction of a metallic hoop material 1 and a moving speed of the spreader 5 is made higher than that of the central part of a widthwise direction of the metallic hoop material 1 at both side end parts. Therefore, the mineral fiber 3 can be spread uniformly between the metallic hoop materials 1 which are in the course of conveyance of the mineral fiber 3 and moreover the mineral fiber 3 is not scattered to the circumference.
