The present invention aims to provide a method for producing auricular cartilage tissue having a sufficient thickness and mechanical strength, and auricular cartilage tissue produced by the method for producing auricular cartilage tissue. The present invention provides a method for producing auricular cartilage tissue, including the steps of: seeding auricular chondrocytes onto a non-woven fabric consisting of a bioabsorbable material having an average fiber diameter of 0.90 to 7.00 &#x3bc;m; and forming a composite of the non-woven fabric seeded with the auricular chondrocytes and a mesh-like framework consisting of a non-bioabsorbable material, and shaping the composite.
