An ultrasonic sensor mounting structure includes an ultrasonic sensor and a wall member to which the ultrasonic sensor is mounted. The ultrasonic sensor includes an ultrasonic transducer and a vibrating surface. An inner surface of the wall member has a fixation portion where the ultrasonic sensor is fixed, a touch portion where the ultrasonic transducer touches, and a location mark portion that indicates location of the fixation portion. An outer surface of the wall member has a vibration portion as the vibrating surface of the ultrasonic sensor. The vibration portion is positioned opposite to the touch portion. The ultrasonic sensor can be accurately mounted in a desired location on the wall member without a reduction in a sensor characteristic, because the location mark portion does not overlap the touch portion.

What is claimed is: 1. An ultrasonic sensor mounting structure, comprising: an ultrasonic sensor that includes an ultrasonic transducer for generating a vibration and a vibrating surface for emitting the vibration; and a wall member having an inner surface and an outer surface opposite to the inner surface, the inner surface having a fixation portion where the ultrasonic sensor is fixed so that the ultrasonic sensor is not visible from the outer surface of the wall member, a touch portion where the ultrasonic transducer directly or indirectly touches so that the vibration generated by the ultrasonic transducer is transmitted to the touch portion, and a location mark portion that defines the fixation portion, the outer surface having a vibration portion positioned corresponding to the touch portion so that the vibration propagates from the touch portion to the vibration portion through the wall member, wherein the location mark portion is located outside the touch portion. 2. The mounting structure according to claim 1, wherein the wall member has a first stiffness at the touch portion and a second stiffness at the location mark portion, and the first stiffness is different from the second stiffness. 3. The mounting structure according to claim 2, wherein the location mark portion is a recessed portion recessed in the wall member or a projecting portion projecting from the wall member. 4. The mounting structure according to claim 2, further comprising: an adhesive member having a liquid state, wherein the location mark portion is an even surface portion that overlaps the fixation portion, and the ultrasonic sensor is fixed to the uneven surface portion through the adhesive member. 5. The mounting structure according to claim 3, further comprising: an adhesive film, wherein the location mark portion is separated from the fixation portion, and the ultrasonic sensor is fixed to the fixation portion through the adhesive film. 6. The mounting structure according to claim 3, wherein the fixation portion is bounded by the location mark portion. 7. The mounting structure according to claim 3, wherein the touch portion is enclosed by the location mark portion. 8. The mounting structure according to claim 2, wherein the location mark portion restricts the ultrasonic sensor to one position with respect to the wall member. 9. The mounting structure according to claim 8, wherein the ultrasonic sensor further includes a hole portion, the location mark portion is an extending portion extending toward the ultrasonic sensor, and the extending portion is inserted into or through the hole portion. 10. The mounting structure according to claim 8, wherein the ultrasonic sensor further includes an extending portion extending toward the inner surface of the wall member, the location mark portion is a hole portion, and the extending portion is inserted into or through the hole portion. 11. The mounting structure according to claim 8, wherein the location mark portion is a guide portion extending along an outer surface of the ultrasonic sensor. 12. The mounting structure according to claim 11, wherein the guide portion has a cylindrical shape with a hollow portion where the ultrasonic sensor is received. 13. The mounting structure according to claim 8, wherein the location mark portion locks the ultrasonic sensor in the position. 14. The mounting structure according to claim 1, wherein the location mark portion determines an orientation in which the ultrasonic sensor is fixed to the wall member, and the orientation allows the ultrasonic sensor to have a predetermined directivity. 15. The mounting structure according to claim 14, wherein the location mark portion is one of a plurality of location mark portions, and the location mark portions are arranged to restrain the ultrasonic sensor in the orientation. 16. The mounting structure according to claim 1, wherein the wall member is a bumper of a vehicle. 17. The ultrasonic sensor mounting structure according to claim 1, wherein the touch portion is positioned directly opposite to the vibrating surface.
