**MEMBER AND METHOD FOR MANUFACTURING SOLID STRUCTURE**

To manufacture a solid structure provided with functions such as shock absorption, sound shielding and heat insulation which can provide the member by which a strong solid structure can be formed easily and disperse and hold the pressure from the outside by using this member.

This solid structure has such form that a triangular prism 2 whose end surface is an isosceles triangle 4 with an apex angle of 120° is installed to the four-side surfaces of a quadrangular prism 1 whose end surface is a square 3 while making this side surface to a bottom surface and is constituted by the combination of such members that the isosceles length of the isosceles triangle 4 is equal to the length of oneside of the square 3 and the height of the quadrangular prism 1 is equal to the length of the bottom side of the isosceles triangle 4. Meantime, the member is integrated as a solid structure by fitting a prism 6 having a square section whose oneside length is equal to the height of the perpendicular (b) of the isosceles triangle to the notch 5 formed between adjacent triangular prism 2.
