A protective structure for an electrical circuit device attached to a vehicle includes a resin case, an electrical circuit, and a rigid body. The electrical circuit is contained in the resin case. The rigid body is contained in the resin case. The rigid body protrudes toward a collision-prone side of the vehicle beyond the resin case. The rigid body deforms or displaces to absorb collision energy when the vehicle is involved in a collision on the collision-prone side.
