A biological information acquiring apparatus includes light source units configured to irradiate light onto a living body, a light receiving unit including a light receiving element, the light receiving element including pixels, each of the pixels receiving at least one of a transmission light and a reflection light, and a nonuniform filter disposed on the light receiving unit and on a light path of at least one of the transmission light and the reflection light, the nonuniform filter having a light transmittance that varies with area of the nonuniform filter. The light source units are disposed around the light receiving unit discretely, and the light transmittance of the nonuniform filter is set so that a light intensity of at least one of the transmission light and the reflection light is uniform over an entire surface of the light receiving element.
