A particulate matter sensor includes a first detection filter provided in an exhaust gas flow passage and capable of collecting particle matter. A second detection filter is provided on a downstream side of the first detection filter in the exhaust gas flow passage and capable of collecting the particle matter. A first differential pressure detection unit is configured to detect a first differential pressure between pressures of an upstream side and the downstream side of the first detection filter. A second differential pressure detection unit is configured to detect a second differential pressure between pressures of an upstream side and a downstream side of the second detection filter. A particle matter amount detection unit is configured to detect an amount of particle matter based on a detection result of the first differential pressure detection unit and a detection result of the second differential pressure detection unit.
