Is brought into contact with the micropore forming device, the fine through fine needle holes forming apparatus in forming micropores in the skin, positioning the tape to indicate the micropores are formed area. A support having a positioning portion for forming a step including at least partially corresponds to the shape of the contact portion of the micropore forming device shape, a mark portion having an opening corresponding to a region in which the micropores are formed It is equipped with a. When the said contact portion of the fine hole forming device is abutted on the positioning tape to form the micropores, the step of the positioning portion restricts the movement of the skin surface direction of the micropore forming device.微細孔形成装置を当接させ、前記微細孔形成装置の微細針により皮膚に微細孔を形成する際に、当該微細孔が形成された領域を示すための位置決めテープ。少なくとも一部が前記微細孔形成装置の当接部の形状に対応した形状を含む段差を形成する位置決め部を有する支持体と、前記微細孔が形成される領域に対応した開口を有する目印部とを備えている。微細孔を形成するために前記微細孔形成装置の前記当接部を位置決めテープ上に当接させた際に、前記位置決め部の段差が当該微細孔形成装置の皮膚面方向の移動を規制する。
