A particulate detection system is provided which detects the amount of particulates when the amount of particulates can be detected properly. A particulate detection system 1 for detecting the amount of particulates S in a gas under measurement EG includes a detection section 10 which is mounted to an exhaust pipe EP, a drive circuit 210, 240 for driving the detection section 10, and a drive control section 225 for controlling the drive circuit 210, 240. The detection section 10 includes a first potential member 31, 12, 13 maintained at a first potential PV1, a second potential member 14, 51, 53 maintained at a second potential PVE, PV3, and an insulating member 121, 77, 76 disposed between the first potential member 31, 12, 13 and the second potential member 14, 51, 53 so as to electrically insulate them from each other. The system 1 includes insulation test means 215, S3, 245, S5 for testing the degree of insulation between the first potential member 31, 12, 13 and the second potential member 14, 51, 53. The drive control section 225 includes drive permission/prohibition determination means S4, S6 for determining, on the basis of the degree of insulation tested by the insulation test means 215, S3, 245, S5, whether to permit the drive of the detection section 10 by the drive circuit 210, 240. |
