METHOD OF PREPARING TEST PIECE

摘要

PROBLEM TO BE SOLVED: To provide a preparation method for a test piece capable of conducting precisely an evaluation test for an evaluated object having a space part in its inside. SOLUTION: The test piece 1 having the space part 2 is prepared by making at first a body 3 different from the test piece 1 exist together with the test piece 1 while exposing at least one portion of the body outside the test piece 1, when the test piece 1 is molded, and by immersing thereafter the test piece 1 existing together with the body 3 into a solution 4 capable of dissolving only the body 3 to elute the body 3 from the test piece 1.
