[Problem] To provide grounding performance similar to that of the conventional counterpart even in a case made of resin. [Means of Solution] An occupant restraint device controller, including an electronic circuit substrate 2 incorporating therein a control circuit that determines whether or not a vehicle 6 has collided based on a detection output of a sensor detecting acceleration/deceleration of the vehicle 6 and outputs a control signal for activating an occupant restraint tool. The electronic circuit substrate 2 is accommodated inside a resin case 1 provided with a structure for leading out a ground electrode from inside to outside. The structure for leading out a ground electrode is configured such that a fixing leg 1b for fixing the electronic circuit substrate 2 is provided inside the case 1, this fixing leg 1b being connected to a mounting portion 1a to be mounted to the vehicle 6, via a ground lead-out member 3 including a first spring structure 3a held between the fixing leg 1b and the electronic circuit substrate 2, a ground terminal 3b held between the case 1 and part of the vehicle 6, and a second spring structure 3c connecting the first spring structure 3a and the ground terminal 3b. [Effect] The need for grounding and sensor performance similar to that of conventional counterparts can be satisfied even if a resin case is employed. |
