< Topic >As by the fact that it possesses the effect of water absorption and the moisturization, the fact that the moisture is quickly lost is prevented the electric conduction effect which the electrode piece is easy to do the wetting, the biomedical signal detects improves, is applied by the detection to the biomedical signal of the human body at the same time in dry area, offers the biomedical signal detector which improves the convenience in regard to use.SolutionsBiomedical signal detector 1, at least one electrode piece 11 and based formation 20 and, includes the assembly structure of one water absorption means 30 at least. It can provide electrode piece 11 in the surface of based formation 20, electrode piece the 1st reception chamber S1 is formed with 11 and based formation 20, water absorption means 30 are registered in the 1st reception interior S1, the top of water absorption means 30 touches to electrode piece 11, cartridge head of water absorption means 30 is contacted based formation 20.< Choice figure >Drawing 2【課題】吸水、保湿の効果を有することで、水分が早く失われることを防ぐとともに電極片が湿潤し易く、生体信号を検知する導電効果が向上し、且つ乾燥地区において人体の生体信号への検知に適用され、使用上の利便性を向上させる生体信号検知器を提供する。【解決手段】生体信号検知器1は、少なくとも一つの電極片11と、ベース層20と、少なくとも一つの吸水手段30との組立構造を含む。電極片11がベース層20の上面に設けられ、電極片11とベース層20との間に第1の受容室S1が形成され、吸水手段30が第1の受容室内S1に位置決めされ、吸水手段30の上端部が電極片11に接し、吸水手段30の底部がベース層20に接触される。【選択図】図2
