PROBLEM TO BE SOLVED: To provide a collision determination device further improving determination accuracy of a collision form of a vehicle.SOLUTION: A first member 11 is locked on an inner panel 22 disposed inside an outer panel 21. A deformation member 13 is fixed to the first member 11 and the outer panel 21, and a closed space 13c changing in volume during a collision of the outer panel 21 is provided in the deformation member 13. A collision determination device includes detection means 14 for detecting internal pressure of the deformation member 13, and further includes determination means 15a for determining that a collision in which the internal pressure detected by the detection means 14 is increased is an overall collision with the outer panel 21 and a collision in which the internal pressure detected by the detection means 14 is reduced is a partial collision with the outer panel 21.SELECTED DRAWING: Figure 1 |
