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 is provided with a sensor portion which has a laser diode generating laser light, a photodiode receiving light, and a sensor housing having a contact surface contacting a subject and which irradiates a subject with the laser light generated by the laser diode through the contact surface, receives reflected light from the subject in the photodiode, and outputs a signal relating to the received light amount, a holding portion holding the sensor housing so as to be movable in an up-and-down direction crossing the contact surface, and a coil spring absorbing and transmitting external force applied to the holding portion to the sensor portion.
