Disclosed is a photoacoustic measurement apparatus that irradiates a light beam onto a subject, from a same side as that of an acoustic wave detector, and that measures photoacoustic waves. The photoacoustic measurement apparatus has: an acoustic wave detector; a diffraction grating member provided in front of a detection surface of the detector; a light source that generates a light beam; and an optical system that guides the light beam from the light source towards the diffraction grating member. The diffraction grating member is configured such that the light beam led to the diffraction grating member is outputted by the diffraction grating member towards a subject surface that opposes the detection surface of the detector. As a result, light beams can strike a biological body in a near-perpendicular angle. This affords greater illumination efficiency, and allows light of substantial light energy to be irradiated deep inside biological structures.

A biological information acquisition apparatus and a biological information acquisition method, both capable of radiating a uniform and efficient light to the whole living body tissue as an object of the detection are provided. The biological information acquisition apparatus of the present invention includes a light source and an acoustic wave detector detecting an acoustic wave generated by making a light from the light source enter the object through an object holding member. Furthermore, one or more light transmitting members are provided, and the light enters the light transmitting member from a side surface side of the acoustic wave detector, and enters the object holding member through the light transmitting member at an angle other than one perpendicular to the object holding member.

A fixing member (3, 40, 43, 50, 53) which fixes a first frame body (1) of a solar battery module main body (9) slides along the first frame body, and the solar battery module main body includes a connecting portion (10) and a to-be connected portion (11) which connects the first frame bodies which are adjacent to each other through the fixing member. With this, a position of the fixing member can freely be moved with respect to the first frame body, the fixing member is slid to a position where there is a structure member (32) which supports a roofboard at predetermined intervals, and the fixing member is mounted at that position. With this, the fixing member can be mounted more strongly, and the adjacent two first frame bodies (31) can be fixed by the fixing member.
