PROBLEM TO BE SOLVED: To provide a wearable sensor capable of performing accurate measurement while suppressing wearing stress on a subject.SOLUTION: A wearable sensor for estimating biological information based on a near infrared ray irradiated to a subject and received through the subject includes: a frame at least put on the auricle; a light receiving/emitting unit having a light emitting part provided to the frame for irradiating a near infrared ray to the subject and a light receiving part for receiving the near infrared ray passing through the subject; a control unit for controlling a timing of the near infrared emission and reception by the light receiving/emitting unit, and estimating biological information based on the near infrared ray received by the light receiving part; and a transmission unit for transmitting the biological information estimated by the control unit.SELECTED DRAWING: Figure 1 【課題】被検者への装着ストレスを抑制しつつ、精度の高い計測を行うことができる装着型センサを提供すること。【解決手段】本発明は、被検体に照射され被検体を経由して受光された近赤外光に基づいて生体関連情報を推定する装着型センサであって、少なくとも耳介に掛けられるフレームと、フレームに設けられ、近赤外光を被検体に照射する発光部、および被検体を経由した近赤外光を受光する受光部を有する受発光部と、受発光部による近赤外光の発光および受光のタイミングを制御するとともに、受光部で受光した近赤外光に基づいて生体関連情報を推定する処理を行う制御部と、制御部で推定した生体関連情報を送信する送信部と、を備える。【選択図】図１
