本发明系一种心跳检测设备，具备1对电极部(4)、发送部(2)和接收部。发送部(2)系借由电线(3)与1对之各电极部(4)电性连接。1对之各电极部(4)具有电极本体部(4a)和件(4b)，用以挟住穿在身体之衣服等之下部，而将电极部(4)保持在身体之特定部位。件(4b)形成在电极部(4)之表侧部分。发送部(2)具有发送本体部(2a)和件(2b)，用以挟住衣服等之上部而将发送部(2)保持在衣服等。件(2b)形成在发送部(2)之内侧部分。借此，可获得一种可将电极部确实地电性接触在胸部之特定部位，而不会产生压迫感，且重量轻之心跳检测设备。

A heartbeat detection device includes a pair of electrode units (4), a transmitting unit (2) and a receiving unit (6). The transmitting unit (2) is electrically connected to the paired electrode units (4) each by respective wires (3). The paired electrode units (4) each include an electrode body (4a) and a hook (4b) sandwiching a bottom part of a garment for example on a body for holding the electrode units (4) on respective predetermined parts of the body. The hook (4b) is formed on the front side of the electrode unit (4). The transmitting unit (2) includes a transmitting-unit body (2a) and a hook (2b) sandwiching an upper part of the garment for holding the transmitting unit (2) on the garment. The hook (2b) is formed on the rear side of the transmitting unit (2). The lightweight heartbeat detection device is thus achieved that can ensure electrical contact between the electrode units and respective predetermined parts of the chest without causing a feeling of tightness.
