<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a plate which is suitable for the large-scale production for manufacturing a fine array-like needle-like body which has a sharp distal end part and a thick base part and shows an excellent strength and a method for manufacturing the biocompatible needle-like body by using the plate. <P>SOLUTION: The method for manufacturing the plate for forming the needle-like bodies integrally molded in an array shape on a substrate 10 includes (1) the process of performing a first process of forming a mask 11 having opening parts at positions where hole shapes corresponding to a plurality of needle-like bodies are formed and of forming the hole shapes which correspond to main bodies of the needle-like bodies, are vertically cut deep, and have the shape of a rectangular solid by using a dry etching method and (2) the process of performing a second process of peeling the mask 11 and forming the distal end part of the needle-like body and a slanting shape at a site corresponding to the base part by crystal anisotropic etching. <P>COPYRIGHT: (C)2008,JPO&INPIT |
