Abstract

　本発明は、臓器壁面と筐体とを接触させる方向に作用する液体の表面張力を軽減でき、臓器内部の液面に浮遊した状態で臓器壁面と筐体とが接触した場合であっても、臓器壁面から筐体を容易に離間できることを目的とする。本発明にかかるカプセル型内視鏡１は、臓器内部の液体に比して比重を小さく設定して、この液体の液面Ｓに筐体２を浮遊させ、筐体２の中心Ｃから外れた位置に重心Ｇを設定して、この液面Ｓに浮遊した状態で筐体２に特定の浮遊姿勢を維持させる。この筐体２と液面Ｓとの境界部Ｂは、この特定の浮遊姿勢をとる筐体２を液面Ｓに対して垂直に投影した投影面Ｋａ内であって投影面Ｋａの外周Ｋｂを除く位置に形成される。
