PROBLEM TO BE SOLVED: To provide a wearable biological sensor capable of suppressing falling of a measurement element and damage of a garment.SOLUTION: A wearable biological sensor in the embodiment comprises: a garment which a biological body can wear； and a measurement part which is attached to the garment, and measures physical activity information which is information related to a physical activity of the biological body which wears the garment. The measurement part comprises a measurement element and a wiring connected to the measurement element, a cylindrical storage part for storing at least a part of the wiring of the measurement part is provided on the garment, and on a halfway position of the storage part in the axial direction, a narrowing part for reducing a diameter of a part of the storage part is formed. The measurement element storage part for storing the measurement element is formed on the storage part by the narrowing part, and a pressure sensor and a biological electrode are overlapped and stored in the measurement element storage part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】測定素子の脱落や衣服の損傷を抑制することができるウエアラブル生体センサを提供する。【解決手段】実施形態のウエアラブル生体センサは、生体が着衣可能な衣服と、前記衣服に取り付けられ、前記衣服を着た生体の身体活動に関する情報である身体活動情報を測定する測定部と、を備える。前記測定部は測定素子及び当該測定素子に接続される配線を備えており、前記測定部の少なくとも前記配線の一部を収容する筒状の収容部が前記衣服に設けられ、前記収容部における軸方向の途中位置に、前記収容部の一部を縮径する絞り部が形成され、前記測定素子を収容する測定素子収容部が前記絞り部によって前記収容部に形成され、前記測定素子収容部に圧力センサと生体電極とが重ねて収容される。【選択図】図１
