The present invention is a moss block which is used for a wall, and the like to achieve greening or soundproof, and the like for appearance decoration by using moss. The moss block comprises a frame, which comprises a space part of a hexahedron shape with an open upper part, the space part receiving a predetermined amount of moss, a plurality of partitions with a predetermined height, which are formed at predetermined intervals at a lower surface part of the frame, and a plurality of slots, which are formed at each upper periphery of both side surfaces opposite to each other of the frame at least one separation member installed to divide the space part of the frame in a direction perpendicularly to the partitions and strings locked between the plurality of slits, which are formed at each periphery of both side surfaces of the frame, to be fixed in parallel. Moss received in the space part, in which the partitions and the separation member are formed, is held by the strings to be uniformly arranged without leaning on one side of the frame and to prevent the moss from escaping from the frame. According to the present invention, sensitive interior design with vivid natural sense is provided by the location or arrangement of moss blocks where Scandinavia moss providing various colors through mineral preservation treatment is fixed, and an aesthetic appearance with abundant volume and soft texture of an analogue design, which may not be expressed by using any artificial material, is provided. Also, the humidity of a target space may be kept, and a soundproof property and a fire-resistant property may be provided.COPYRIGHT KIPO 2015본 발명은 모스(Moss, 이끼)를 이용하여 벽면 등에 미관 장식을 위한 녹화나 방음 등을 위하여 친환경 모스블록에 관한 것으로, 상부가 개방된 육면체 형상으로 일정량의 모스를 수용하는 공간부가 형성되고, 하부 상면에 일정 간격을 두고 복수의 격벽이 일정 높이로 형성되며, 마주하는 양측면 상부 가장자리에 일정 간격으로 복수의 슬릿이 형성된 틀 상기 격벽과 직교하는 방향으로 틀의 공간부를 구획하도록 설치된 하나 이상의 분리부재, 및 상기 양측면 가장자리에 형성된 복수의 슬릿과 슬릿에 걸쳐 평행하게 고정되는 스트링을 포함하고, 상기 격벽 및 분리부재가 형성된 공간부에 수용되는 모스를 스트링으로 고정하여 모스가 틀 한
