Summary:To provide a blood flow sensor in which a fluctuation of measurement results is suppressed during measurement of the blood flow volume. A probe portion 11 is provided with a sensor portion 21 which has a laser diode generating laser light, a photodiode receiving light, and a sensor housing 27 having a contact surface 44 contacting a subject and which irradiates a subject 82 with the laser light generated by the laser diode through the contact surface 44, receives reflected light from the subject 82 in the photodiode, and outputs a signal relating to the received light amount, a holding portion 22 holding the sensor housing 27 so as to be movable in an up-and-down direction 7 crossing the contact surface 44, and a coil spring 23 absorbing and transmitting external force applied to the holding portion 22 to the sensor portion 21.
