Zusammenfassung:	A piercing needle having a low piercing resistance even if repeatedly caused to pierce is provided. The piercing needle has an undercoat of a silane coupling agent, preferably, an amino group-containing alkoxysilane or an epoxy group-containing alkoxysilane, and an outer surface of a mixture of (1) a reactive silicone such as a reaction product of an amino group-containing alkoxysilane, an epoxy group-containing alkoxysilane and a silicone having silanol groups at both terminal ends, with (2) a non-reactive silicone.
