1. A sensor module for a vehicle, comprising:
- a base plate;
a sensor attached to the base plate and including;
a plurality of piezoelectric films for detecting an external force applied to a vehicle body of the vehicle, each piezoelectric film having an electrode attached thereto;
a plurality of signal lines;
a flexible base film; and
a protective film for protecting the piezoelectric films and the signal lines formed on a surface of the base film; and
a signal processing unit attached to the base plate and connected to the sensor for processing sensor signals output from the sensor;
wherein each of the plurality of signal lines connects the electrode of each of the plurality of piezoelectric films to the the signal processing unit for transmitting to the sensor the sensor signals outputs from the sensor, andthe plurality of signal lines are aligned longitudinally with the plurality of piezoelectric films.
