PROBLEM TO BE SOLVED: To provide a needle-like body whose mount part is not deformed during the operation of sticking the needle-like body and which little stimulate the skin even when stuck to the skin for a long period of time, and to provide a method for easily manufacturing the needle-like body.SOLUTION: The method for manufacturing the needle-like body is characterized in that a vacancy is formed at the mount part of the needle-like body by molding a resin configuring the needle-like body in the recessed parts of a duplicate version including the recessed parts arrayed in a fine array shape in which the recesses and projections of the shape of the needle-like body are inverted, and pressurizing, from the resin surface side, a support plate having projection parts for forming the vacancy passing through the resin layer of a flat part at the part where the needle-like body of the duplicate version is not formed. With the use of the method, the fine needle-like body integrally molded in the array shape and provided with the vacancy on the mount part of the needle-like body is manufactured.COPYRIGHT: (C)2010,JPO&INPIT【課題】針状体を貼り付ける操作の間、台座部が変形しない針状体であり、かつ長時間皮膚に貼り付けても皮膚刺激が少ない針状体と、その針状体を簡便に作製する方法を提供すること。【解決手段】針状体の形状を凹凸反転させた微細なアレイ状に配列した凹部を含む複製版の凹部に針状体を構成する樹脂を成型し、その樹脂面側から、複製版の針状体が形成されていない部分の平坦部の樹脂層を貫通する空孔を形成できる凸部を備える支持版を押圧する事により、針状体の台座部に空孔を形成することを特徴とする針状体の製造方法を用いて、アレイ状に一体成型される微細な針状体であって、針状体の台座部に空孔を備える針状体を製造する。【選択図】図1
