PROBLEM TO BE SOLVED: To provide a structure of a graveyard tasteful at sight without growing weeds by noticing antimicrobial properties of a bamboo material formed into a chip state and further adding the use of a ceramic liquid utilizing catalyst actions of silver in combination. SOLUTION: This structure of grave soil is composed of a surface layer 1 formed of a bamboo material in the chip state or a powdery state containing an antimicrobial component for suppressing the propagation of microorganisms, an intermediate sand layer 2 for leveling unevennesses, an intermediate carbon layer 3 having absorptivity of water and moisture and humectant properties and a lower layer 4 formed of gravels having draining properties. The bamboo material in the surface layer 1 is then coated with a ceramic liquid obtained by suitably preparing a far infrared radiating silicon dioxide and an antistatic aluminum silicate and/or aluminum oxide having 0.02-0.15μm particle diameter and silver oxide and/or copper oxide having 0.1-0.5μm particle diameter and exhibiting oxygen active catalyst actions and an acrylic resin for binding.
