Abstract
Disclosed is a method of manufacturing a heat insulation wall body, by which the heat insulation wall body can be manufactured economically. The method is a manufacturing method of a heat insulation wall body having a groove portion formed by a first side wall, a second side wall and a groove bottom. The method includes dispersing and mixing a heat insulating material in an aqueous medium to prepare a slurried heat insulating material, bringing a molding die having a vent and a surface corresponding to a shape of the groove portion, into the obtained slurried heat insulating material, and dehydrating the slurried heat insulating material via the vent, and releasing the molding die from the heat insulating material to prepare the heat insulation wall body in which a depth of the groove portion is fixed, and a width of the groove bottom is varied in a longitudinal direction of the groove portion.
