<p>A pedestrian collision detection device is obtained that is capable of improving pedestrian detection performance in the vicinity of a bumper corner portion. A pedestrian collision detection device (10) includes a chamber member (20) disposed with pressure detectors (24), and an ECU (26) is connected to the pressure detectors (24). Terminal portions (20A) of the chamber member (20) are wrapped around so as to cover vehicle width direction outside end faces (14B) of bumper reinforcement (14) at bumper corner portion (12A) sides. When a load of a specific value or greater is input to the terminal portions (20A) of the chamber member (20) from a bumper cover (18) side during a collision, the terminal portions (20A) obtain a reactive force from the bumper reinforcement (14) and undergo compression deformation towards the vehicle width direction inside, and the pressure inside a pressure chamber of the chamber member (20) changes.</p> |
