PROBLEM TO BE SOLVED: To provide a discrimination method of a concrete test piece capable of performing discrimination work simply, accurately and certainly by causing no fear of an artificial mistake at the time of discrimination, and by achieving the efficiency of recognition work. SOLUTION: Ready-mixed concrete 12 is cast in forms 11 and 11 for the concrete test piece and a thin plate-shaped IC tag 1 is subsequently embedded in the ready-mixed concrete 12 from the cast surface 12a of the ready-mixed concrete 12 so that the antenna part of the IC tag 1 becomes parallel to the inner surfaces 11a of the forms 11. Next, the ready-mixed concrete 12 is cured and demolded to form the concrete test piece and the data recorded on the IC tag 1 of the concrete test piece is subsequently read in a non-contact state using an IC tag reader/writer to identify the concrete test piece on the basis of the read data.
