<p>Provided is a biosensor capable of reducing stray light received without passing through an organism, and that can improve reliability without an increase in size. A biosensor (100) comprises: a wiring board (110); a light-emitting element (121) and a light-receiving element (122) mounted at predetermined intervals on a main surface (110a) of the wiring board (110); a transparent light-emitting sealing part (131) formed only on the upper part of the region for mounting the light-emitting element (121); a transparent light-receiving element sealing part (132) formed only on the upper part of the region for mounting the light-receiving element (122); and a light-blocking part (133) formed on the main surface (110a) of the wiring board (110), and disposed around the transparent light-emitting sealing part (131), around the transparent light-receiving element sealing part (132), and between the transparent light-emitting sealing part (131) and the light-receiving element sealing part (132).</p> |
