This biological information acquisition device (10) is provided with a tube-shaped pressure-sensitive tube (50) which is arranged between an installation unit (32, 34) and a pressure receiving plate (70) and on which bodily movement of a subject (S) acts through the pressure receiving plate (70), a pressure detection unit (61) which receives the internal pressure of the pressure sensitive tube (50) and outputs a signal corresponding to said internal pressure, and a signal processing unit (69) which acquires biological information about the subject (S) on the basis of the signal outputted by the pressure detection unit (61). In the area near the lateral ends (71, 72) of the pressure receiving plate (70) and the pressure sensitive tube (50), a shear force suppressing part (80) is provided which reduces the shear force acting from the lateral ends (71, 72) of the pressure receiving plate (70) on the pressure sensitive tube (50). |
