Abstract:
A particulate sensor (1) having a sensor-side positioning portion (11k) for determining the circumferential position of a sensor main body (5) with respect to a sensor attachment portion (120) when the particulate sensor (1) is attached to the sensor attachment portion (120). The sensor attachment portion (120) has a pipe-side positioning portion (121) which conforms to the sensor-side positioning portion (11k) and is configured such that, when the particulate sensor (1) is attached to the sensor attachment portion (120), the circumferential position of the sensor main body (5) with respect to the sensor attachment portion (120) is always set to a fixed circumferential position.
