To provide a biological information acquiring device capable of acquiring a high-quality image by a reliable method.
The biological information acquiring device 90 acquires biological information of a subject, based on light irradiation with respect to the subject, including a light source 5 for radiating light to be irradiated toward the subject; and a position adjusting means for adjusting the position of the light source 5 with respect to the subject. The position adjusting means appropriately sets the position of the light source with respect to the subject. When vein authentication is performed, emission light from the light source is sufficiently diffused inside the subject (e.g., a human hand, foot, and its fingers (toes)). Consequently, the high-quality image is acquired by the reliably method.
