To provide a living body sensing apparatus capable of increasing a body surface temperature.SOLUTION: A living body sensing apparatus includes a light emitting element for irradiating a living body with light, a light receiving element for receiving the light from the living body, a connection part configured so as to come in contact with the living body, and a heat transfer part that connects the light emitting element to the connection part, and transfers heat of the light emitting element to the connection part. The light emitting element includes a base plate, a first mirror layer provided to the base plate, an active layer provided at a side opposite to a base plate side of the first mirror layer, and a second mirror layer provided at a side opposite to a first mirror layer side of the active layer. The heat transfer part connects a second mirror layer side of the light emitting element to the connection part.SELECTED DRAWING: Figure 4【課題】体表面温度を上げることができる生体センシング機器を提供する。【解決手段】生体に光を照射する発光素子と、前記生体からの光を受ける受光素子と、前記生体と接触可能に構成されている接触部と、前記発光素子と前記接触部とを接続し、前記発光素子の熱を前記接触部に伝える伝熱部と、を有し、前記発光素子は、基板と、前記基板に設けられた第１ミラー層と、前記第１ミラー層の前記基板側とは反対側に設けられた活性層と、前記活性層の前記第１ミラー層側とは反対側に設けられた第２ミラー層と、を有し、前記伝熱部は、前記発光素子の前記第２ミラー層側と前記接触部とを接続している、生体センシング機器。【選択図】図４
