PROBLEM TO BE SOLVED: To provide an analyte information acquisition apparatus, when performing photoacoustic measurement, suppressing influence of electromagnetic noise from a light source on a photosensor.SOLUTION: The analyte information acquisition apparatus includes: a light source unit including a light source and a drive circuit for driving the light source a probe for converting an acoustic wave into an electric signal, the acoustic wave generated from an analyte by receiving irradiation of light emitted from the light source light detection means for detecting the light emitted from the light source to generate a trigger signal a controller for receiving the trigger signal from the light detection means and the electric signal from the probe to generate characteristic information of the inside of the analyte and a housing for shielding electromagnetic noise generated from the light source unit. The housing stores the light detection means so as to isolate the light detection means from the light source unit.SELECTED DRAWING: Figure 1
