Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a medical ceramic-coated puncture needle that eases pains of the skin pierced with it and makes it possible to present clear ultrasonic images for monitoring patients. SOLUTION: A medical ceramic-coated puncture needle excellent in wear resistance and adhesion is available by coating the direct surface of the needle with a SiNx mixed layer 4, next coating it with a SiNx ceramic layer 3, then coating it with a composite SiNx and DLC film layer 2, and finally coating the outermost surface with a DLC layer 1. If this needle is used, it is possible to ease pains of the skin when pierced with the needle. Further when patients are monitored with the ultrasonic images using this needle, clear ultrasonic images are available, facilitating the inspection and treatments of patients.
