PROBLEM TO BE SOLVED: To reduce time for forming a window for detection, and at the same time to form the window for detection that can perform accurate detection. SOLUTION: In a manufacturing method, capillary columns 102 adhere one another for forming a line on a flat plate 204 so that a region 102a that is intended to form a window for detection is positioned on the long hole of the flat plate 204, the long hole of a flat plate 206 is placed so that it is positioned in the region 102a that is intended to form the window for detection, and the capillary columns 102 are put between the flat plates 204 and 206 for fixing. The longitudinal direction of a heated Nichrome wire coil 208 is brought into contact with the end part of the region 102a that intended to form the window for detection via the long hole of the flat plate 206 while orthogonally crossing to the capillary column 102, and a covering is burned for eliminating. The Nichrome wire coil 208 is moved along the long hole of the flat plate 206 while one part of the contact region of the Nichrome wire coil 208 is overlapped so that the covering does not remain in the region 102a that intended to form the window for detection. At this time, the covering on the surface of an opposite side where the Nichrome wire coil 208 is brought into contact is also eliminated. |
