摘要：<p>PROBLEM TO BE SOLVED: To provide a fixture used for manufacturing a testing lithium ion battery observed with a microscope from a direction parallel to an extension direction of a positive electrode plate and a negative electrode plate.SOLUTION: An observation jig of a testing lithium ion battery includes: first and second fastening members (11, 12) which are engaged with each other to hold a battery structure therebetween; and fastening screws (13a, 13b) which mutually fix the first and second fastening members. The first and second fastening members respectively have flat surfaces (11a, 12a) which are orthogonal to an extension direction of the battery structure and form a reference surface (14) having the same height level when they are engaged with each other and fastened. The reference surface (14) functions as a reference surface to determine the positions of edges of the battery structure and an insulation film to be observed with a microscope, and functions as a joining surface to which a transparent plate constituting an observation window is fixed.</p>
