PROBLEM TO BE SOLVED: To provide a heart model for phantom test capable of preventing the leakage of a content liquid.SOLUTION: The present invention relates to a heart model 10 used by a tomographic apparatus for performing tomography of a living body. The heart model 10 has a main body container 100 having a shape simulating the left ventricle with a duplex shell structure in which an outer shell 101 simulating an outer wall of the left ventricle and an inner shell 102 simulating an inner wall of the left ventricle are arranged via a gap 104 and a lid part 200 mounted on the main body container 100 so as to cover at least the gap 104. A storage part 104 for storing a radioactive liquid is provided in the gap between the outer shell 101 and the inner shell 102. Further, the main body container 100 includes a plurality of through holes 201 for injecting the radioactive liquid into the storage part 104. The direct bonding of the outer shell 101 and the lid part 200 and the direct bonding of the inner shell 102 and the lid part 200 make the main body container 100 and the lid part 200 integrate.
