電図を得られないという欠点があった。2. Description of the Related Art In a conventional bioelectrode, silver-silver chloride, which is generally widely used, is formed in a predetermined thickness, for example, 10 to 20 microns, over the entire surface of the electrode, and the electrode is used as an electrode element (" Silver-silver chloride electrode ") and did not have X-ray transparency. For this reason, if X-ray photography is performed with the electrodes attached to the living body, the shadows of the electrodes will appear in the X-ray photographs. Therefore, in order to prevent a misdiagnosis, the patient must be attached to the living body while avoiding the portion where the X-ray imaging is performed.

Such an electrode is mainly used as an electrode for monitoring a catheter and monitoring during surgery. FIG. 4 shows an exploded view of this conventional electrode. As shown in FIG. 4, a conventional biological electrode of this type includes a base material 11 made of paper, polymer film, or the like, and a lead wire 1 made of carbon fiber.

点がある。As shown in FIG. 4, a conventional X-ray transmission type bioelectrode is different from a general biodeposition electrode because an electrode element and a lead wire portion are made of X-ray permeable carbon fibers. Even if X-ray photography is performed with the electrode attached to the living body, the shadow of the electrode is less likely to appear on the X-ray photograph, and misdiagnosis can be prevented. Therefore, there is an advantage that it is not necessary to remove the electrode every time X-ray imaging is performed, and a complicated operation can be omitted.

おける波形の安定性が悪い等の問題があった。However, the conventional X-ray transmission type bioelectrode is different from the above-mentioned generally used electrode using silver-silver chloride as an electrode element ("silver-silver chloride electrode"). In comparison, although having the above advantages, there are problems such as inferior electrical performance and poor waveform stability in recording / monitoring of an electrocardiogram.

Although it becomes impossible, it recovers in a short time when a silver-silver chloride electrode is used, whereas when an X-ray transmission electrode is used, the electrochemical reaction between the electrode element and the electrolyte substance The problem is that there is a problem with the electrical connection, it takes a long time before the recording of the electrocardiogram becomes possible, and the problem that the monitoring of the electrocardiogram becomes impossible despite the necessity of quick diagnosis etc. Had.
