A three-dimensional view of the stomach in a folded state, and FIG. 9 is a side view of a flexible substrate in a bent state according to a preferred embodiment of the present invention. Referring to FIG. 7 and FIG. 8 at the same time, the trunk portion 206a of the bending portion 206 is bent through the gap s of the two branch portions 206b, and passes through the gap s of the two branch portions 206b after one turn. 7 and 8 show the bending state of the flexible substrate 200 from different viewing angles. Please refer to FIG. 9 at the same time. From this side view, the bending method of the flexible substrate of the present invention can be seen clearly: the second fixing portion 204 is bent and the main portion 206a of the bending portion 206 is bent. Pass through the gap s of the two branch portions 206b, and then pass through the gap s ° of the two branch portions 206b after one turn. According to the characteristics of the present invention, since the width of the trunk portion is smaller than the gap of the two branch portions, the folding can be avoided. The main part of the bend rubbed against the two branches. The above-mentioned slightly Y-shaped bent portion 206 is only an example. According to the spirit of the present invention, the bent portion of the flexible substrate of the present invention is not limited to the slightly Y-shaped shape in the above embodiment. For example, an opening may be formed in the bending portion connecting the first fixing portion and the second fixing portion, and the opening is from the connection point of the bending portion and the first fixing portion toward the bending portion and the second fixing portion. The connection extends. By making the width of the second fixing part smaller than the narrowest part of the width of the opening, it is possible to avoid the first notice.
