PROBLEM TO BE SOLVED: To provide a biological signal transmitter which is highly convenient and hygienic, and can suppress costs by making it possible to be removed from/attached to an electrode instrument, such as a snap-type and a tab-type electrode pads.SOLUTION: A biological signal transmitter 30 is provided with a radio transmission part which transmits to a receiver a biological signal inputted by, for example, a snap-type electrode pad 21 or a tab-type electrode pad that can be attached onto the skin surface of a living organism as a radio signal. The biological signal transmitter 30 is provided with: a contact terminal part 31 which has a contact electrode 311 that is in contact with a terminal part 212 of the electrode pad 21 and protrudes from a device body part 33 and an elastic projection part 32 which is provided for the device body part 33 via a slit gap between the contact terminal part 31 and the device, and grips the terminal part 212 with a recess 323 formed at an end part together with the contact electrode 311 in the state that the contact electrode 311 is in contact with the terminal part 212.COPYRIGHT: (C)2015,JPO&INPIT【課題】高い利便性を有すると共に、スナップ型とタブ型の電極パッドなどの電極器具と脱着可能とすることにより、衛生的でコストが抑えられる生体信号送信装置を提供する。【解決手段】生体信号送信装置30は、生体の皮膚面に取り付けられる、例えば、スナップ型の電極パッド21またはタブ型の電極パッドから入力した生体信号を無線信号として受信装置に送信する無線送信部を備えている。生体信号送信装置30は、電極パッド21の端子部212に接触する接触電極311を有し、装置本体部33から突出した接触端子部31と、接触端子部31との間で、スリット状の隙間を介して装置本体部33に設けられ、接触電極311を端子部212に接触させた状態で、端子部212を、接触電極311と共に、先端部に形成された凹部323により挟み込む弾性突状部32とを備えている。【選択図】図5
