Abstract
A heat insulation material which is formed of a laminated body in which a plurality of plate-like bodies are stacked, can exhibit a heat insulation property, and is sufficiently eco-friendly. In each of the plate-like bodies, a plurality of rod-like foams, obtained by extrusion-foaming a foam material, are oriented in one direction to be fanned integrally with each other, and the plate-like bodies neighboring in the lamination direction are stacked so that an orientation direction of the foams of one plate-like body and an orientation direction of the foams of the other plate-like body are nearly perpendicular to each other.
