and a branch portion 52 branching from the base into a number of electrodes.
-54, electrode parts 55-57 disposed near the tips of the branch parts 52-54, and the electrode parts 55-57 and the connecting terminal part 51
The conductive wire patterns 58 to 60 are arranged between the conductive wire patterns 58 to 60. Further, the sheet surface portion excluding the electrode portions 55 to 57 indicated by diagonal lines in the figure and the connection portion 51 at the base portion is coated with an electrically insulating film.

に使い易いものである。The sheet-like electrode constructed as described above can be bent freely and easily attached to a desired location on the subject. Moreover, since the flexible substrate having a predetermined width is used between the electrode section and the connector section, entanglement of the electrodes does not occur as would occur when the electrodes are connected using wires or the like. Furthermore, since the shape corresponds to the mounting position, the mounting work is facilitated, so it is very easy to use.
そして係るシート状電極５０を心電計等の生体情報処理
装置と接続するには、該シート状電極５０と生体信号処
理装置サイドとを電気的に接続するためのコネクタが必
須のものであった。In order to connect the sheet-shaped electrode 50 to a biological information processing device such as an electrocardiograph, a connector for electrically connecting the sheet-shaped electrode 50 and the biological signal processing device side is essential. .

った。Conventional connectors of this type have a gap with the thickness of the base of the flexible sheet substrate, and when the flexible sheet substrate is inserted, a conductive pattern portion of the flexible sheet substrate has a conductive pattern for electrically connecting to the processing equipment. A conductive pattern contact piece made of metal was placed there.
そして、従来はシート状電極を上記コネクタに接続する
ためには、シート状電極の基部を該接続コネクタの間隙
部分に圧太しなければならなかった。Conventionally, in order to connect a sheet-like electrode to the connector, it was necessary to press the base of the sheet-like electrode into the gap between the connectors.

等による接触不良が多く発生していた。[Problem to be Solved by the Invention 1] However, if the connection connector conductive pattern at the base of the sheet electrode and the conductive pattern contact piece are slid, so to speak, each time the sheet electrode is connected to the connector, the conductivity of both contact parts will be reduced. Contact defects often occurred due to the contact parts peeling off due to wear, or the surface becoming uneven.

Situations where the parts did not come into contact began to occur, resulting in poor contact.
