A weft yarn detection device (30) for an air jet loom (10) includes a weft yarn sensor (31) disposed so that a sensor end portion of the weft yarn sensor (31) faces a reed passage (13b), and including a light projection unit (32a) configured to project light toward the reed passage (13b), and a light receiving unit (32b) configured to receive the light in the sensor end portion, and a reflective member (40) disposed between the reed dents (15) disposed side by side in the weft insertion direction (X) at a position where the light is projected from the light projection unit (32a) though the reed passage (13b), and having an arcuate surface (45) reflecting the light toward the light receiving unit (32b). The arcuate surface (45) is recessed in a direction away from the light projection unit (32a), as viewed in the weft insertion direction (X).
