Claim:
An organ regeneration device for regenerating a defective portion of an organ, the organ regeneration device being adapted to be used by placing it into the defective portion, comprising: a base body having a front face, a rear face opposite to the front face and a shape corresponding to a shape of the defective portion of the organ, and the base body having a thickness direction from the front face to the rear face, the base body being a bioabsorbable material; particles composed of a different material from that of the base body; and a first growth-related substance contained in the organ regeneration device for growth and differentiation of cells around the defective portion, the first growth-related substance carried on the base body, wherein at least a part of each of the particles has penetrated the surface of the front face of the base body or the rear face of the base body so as not to be overlapped with each other in the thickness direction of the base body, the organ is constituted of an ectodermal tissue and an endodermal tissue being in contact with the ectodermal tissue, and the first growth-related substance contains at least one of an angiogenesis factor and a first nucleic acid containing a base sequence coding for amino-acid sequence of the angiogenesis factor.
