A collision determination apparatus to be mounted in a vehicle includes a wiring substrate, a first acceleration sensor, a second acceleration sensor, an analog-to-digital converter, and a central processing unit. The wiring substrate has a first surface and a second surface opposite from each other. The first acceleration sensor is mounted on one of the first surface and the second surface. The second acceleration sensor is mounted on the other one of the first surface and the second surface in a state where the second acceleration sensor is rotated 90 degrees with respect to the first acceleration sensor. The analog-to-digital converter converts an analog signal from the first acceleration sensor or the second acceleration sensor to a digital signal. The central processing unit determines a collision by an arithmetic processing of the digital signal. |
