A particulate detector that is used to detect a particulate in gas, the particulate detector includes an electric-charge generator that applies an electric charge generated by electric discharge to the particulate in the gas that is introduced into a gas flow path to obtain a charged particulate and a first collector that collects an excess electric charge that is not applied to the particulate and a second collector that collects the charged particulate and a detection unit that corrects a second physical quantity that varies in response to the charged particulate collected by the second collector on the basis of a first physical quantity that varies in response to the excess electric charge collected by the first collector and that detects an amount of the particulate on the basis of the corrected second physical quantity.

A stack structure includes plate-like electrochemical cells of ceramic, each having a pair of main surfaces and a side surface, and plate-like retainer pieces. The cell includes a first electrode in contact with first gas, a solid electrolyte, and a second electrode in contact with second gas. The first electrode has a gas flow channel formed therein and adapted to allow flow of the first gas. The cell has gas inflow and outflow ports. The retainer piece includes a body portion having a through-hole formed therein, and a pair of protrusions protruding from the body portion. The retainer piece has a communication hole formed therein and adapted to establish communication between the through-hole and a space formed between the protrusions. The cell is held by the paired protrusions, thereby establishing communication between the gas inflow or outflow port of the cell and the communication hole of the retainer piece.
