<p>A fluorescent sensor (30) is provided with: a detection substrate section (11), wherein a PD element (12), which converts fluorescence into electric signals, is formed on a wall surface (22) of a through hole (21) that penetrates a first main surface (11SA) and a second main surface (11SB); an indicator (17), which is disposed inside of the through hole (21), and which generates fluorescence with intensity corresponding to the concentration of an analyte when the excitation light is received; a filter layer (14), which covers the PD element (12), passes through the fluorescence, and blocks the excitation light; a light blocking layer (18), which covers an opening of the through hole (21), said opening being in the first main surface (11SA), and which the analyte can pass through; and an LED chip (15), which covers a region just below the opening of the through hole (21), said opening being in the second main surface (11SB), and which generates the excitation light.</p> |
