Abstract: A porous composite which comprises a porous layer comprising a calcium phosphate ceramic and, formed on part of the surface thereof, a dense layer having a smaller average pore diameter than the porous layer. The porous composite can be produced by (1) introducing a slurry containing a calcium phosphate ceramic/collagen composite and collagen into a mold having a high thermal conductivity, (2) rapidly freezing the slurry in the mold and drying it to form a porous object comprising a porous layer and a dense layer formed on the surface thereof, (3) crosslinking the collagen contained in the porous object, and (4) cutting the porous object to partly remove the dense layer and expose the porous layer so as to leave the dense layer in the area where the porous object comes into contact with a soft tissue after having been implanted in the body.

Abstract: PROBLEM TO BE SOLVED: To provide a sample container capable of safely transporting a sample and easy to take out the sample.
SOLUTION: A groove in which a pincette for taking out the sample can be inserted so as to match the shape of the inner wall of a housing container with the shape of the sample to make it hard to move the sample not only to enable the safe feed of the sample but also to facilitate the taking-out of the sample. The sample container for housing the sample is obtained by utilizing this constitution and has a sample placing part 5a having an inner wall slightly larger than the sample and the housing part 5 provided to the side surface part opposed to the inner wall and having the groove 5b in which the pincette for taking out the sample can be inserted.
