PROBLEM TO BE SOLVED: To provide a biological information detection apparatus which ensures waterproofing performance while enabling miniaturization.SOLUTION: The biological information detection apparatus comprises: a biological signal detection unit 50 having a detection electrode 50a which is brought into contact with a living body surface a circuit substrate 40 into which biological signals detected by the biological signal detection unit 50 are input and a case 20 for receiving a circuit substrate 40. The case 20 includes case through-holes 29 which make the inside and the outside of the case 20 communicate with each other. The circuit substrate 40 includes a substrate through-hole 41 with a connection electrode 41a formed on its inner peripheral surface. The biological signal detection unit 50 is made from an electrically conductive elastic material and has a cylindrical connection part 51 electrically connected to the detection electrode 50a. The connection part 51 is inserted into the substrate through-hole 41 through a case through-hole 29. In addition, a pin member 61 is inserted into a cylindrical interior of the connection part 51, and the outer peripheral surface of the connection part 51 contacts the entire inner peripheral surface of the case through-hole 29 and also contacts the inner peripheral surface of the substrate through-hole 41.COPYRIGHT: (C)2016,JPO&INPIT【課題】防水性を確保しつつ、小型化が可能な生体情報検出装置を提供する。【解決手段】生体情報検出装置は、生体表面に接触する検出電極50aを有する生体信号検出部50と、生体信号検出部50により検出された生体信号が入力される回路基板40と、回路基板40を収容するケース20と、を備える。ケース20は、内外を連通するケース貫通孔29を有する。回路基板40は、内周面に接続電極41aが形成された基板貫通孔41を有する。生体信号検出部50は、導電性を有する弾性材料により形成され、検出電極50aと電気的に接続された筒状の接続部51を有する。そして、接続部51は、ケース貫通孔29を通じて基板貫通孔41に挿通されるとともに、接続部51の筒状内部にピン部材61が挿入され、接続部51の外周面は、ケース貫通孔29の内周面の全周に亘って接触するとともに、基板貫通孔41の内周面に接触する。【選択図】図3
