1. A pedestrian collision detection sensor-equipped vehicle bumper structure comprising:
bumper reinforcement that is disposed with a length direction along a vehicle width direction at a vehicle front-rear direction inside of a bumper cover provided at a front-rear direction outside end of a vehicle;
an absorber that is disposed adjacent to the vehicle front-rear direction outside of the bumper reinforcement and that extends along the vehicle width direction;
a pedestrian collision detection sensor that is configured including a pressure tube extending along the vehicle width direction between the bumper reinforcement and the absorber, bending toward a vehicle lower side at positions of both vehicle width direction end portions of the bumper reinforcement, and including a left and right pair of tube end portions extending along a vehicle up-down direction, and that outputs a signal according to a change in pressure in the pressure tube; and
a reinforcement member that is provided to a vehicle front-rear direction inside face of the bumper cover, that reinforces the bumper cover, and that is disposed in a position superimposed in the vehicle front-rear direction on the tube end portion in plan view.
