PROBLEM TO BE SOLVED: To provide an electrode for a living body which makes close contact with a living body regardless of a region to be measured.SOLUTION: The electrode 100 for a living body is configured to cover the circumference of a holding part 20 having a resilience and a thickness such as a sponge with a detecting part 10 having conductive properties and flexibility such as a fabric made of a conductive fiber for detecting the difference in electrical potentials of the living body. In addition, the electrode 100 is disposed inside clothes to make contact with the living body. The holding part 20 and the detecting part 10 have elasticity and flexibility to keep the contact between the living body and the detecting part 10.COPYRIGHT: (C)2011,JPO&INPIT【課題】測定する部位によらずに生体に密着する生体用電極を提供する。【解決手段】本発明に係る生体用電極100は、スポンジなどの弾力と厚みとを持つ保持部20の周囲を、導電性繊維による布などの導電性と柔軟性とを持ち、生体の電位差を検出する検出部10で覆う構成を有する。また、生体用電極100は生体と接触するように衣服の内側に設置され、生体と検出部10との接触が保持されるように、保持部20と検出部10とは、弾力性と柔軟性とを備える。【選択図】図1
