An electrophoresis chip which is inexpensive and easy to manufacture, a method for manufacturing the same, and a method for analyzing a substance are provided. The electrophoresis chip includes a plate-like cover member, a plate-like intermediate member, and a plate-like base member, and the plate-like intermediate member is provided at a narrow groove-shaped through hole and at both ends thereof. And the flat cover member forms a liquid pool portion together with the liquid pool portion forming through hole provided in the flat intermediate member. It has through-holes 4a and 4b for forming a liquid pool, and each opening of the narrow groove-like through-hole is closed by a flat cover member and a flat base member to form a capillary. In the manufacturing method, the flat cover member, the flat intermediate member, and the flat base member are joined. The analysis method uses the electrophoresis chip. [Selection diagram] Fig. 1 |
