The present invention relates to an artificial shell and a spacer thereof, wherein the artificial shell comprises: a boss (10) forming a penetrated hole (11), through which a suspended line (60) passes, at the center an external wall (20) arranged at the same height as the boss on a regular radius from the circumference of the boss (10) partitions (30) connecting the boss (10) and the external (20) to each other to divide the space therebetween radially at a regular angle and a shellfish seed implantation unit (40) installing a plurality of inclined surfaces (41) with a regular inclined angle in parallel to be spaced at regular intervals for making a plate surface viewable from an upper part of the boss (10), between each of the partitions (30), to the external wall (20), forming an upper and a lower cover surface (42) by connecting the upper end parts and the lower end parts of the inclined surfaces (41) to the upper end parts and the lower end parts of the partitions (20) while extending the upper end parts and the lower end parts of the inclined surfaces (41) toward the boss (10) and the external wall (20) to have a regular radius, and forming a plurality of penetrated holes (43) on the cover surface (42) at regular intervals. The artificial shells have a characteristic of being alternately connected on the suspended line (60) by the spacer (50) including: a body (51) with a regular height forming an axial hole at the center through which the suspended line (60) passes and support parts (52), with a diameter larger than an external diameter of the boss (10) at the center through which the suspended line (60) of the artificial shell passes, gradually reducing the thickness toward the outside as being multiply extended to make the circumference of the body (51) equidistant in a radial direction.COPYRIGHT KIPO 2015본 발명은 인공패각 및 그의 간격 유지구에 관한 것으로서, 중앙에는 수하연(60)이 통과하는 관통홀(11)을 형성한 보스(10) 상기 보스(10)의 외주면으로부터 일정 반경에서 동일한 높이로 구비되는 외벽(20) 상기 보스(10)와 외벽(20) 사이의 공간을 방사상으로 균일한
