A biological information imaging method includes a first measurement step to measure an acoustic wave (54) generated by light (53) with which a living body (51) is irradiated from a light source (50) and which is absorbed by tissue (52) in the living body, a storage step to store first information obtained in the first measurement step, a second measurement step to measure an acoustic wave (54) generated by light (53) with which the living body (51) is irradiated from the light source (50) and which is absorbed by the tissue (52) in the living body, and a processing step to generate an image of information of the tissue in the living body by using second information obtained in the second measurement step, and the first information stored in the storage step.
