Claim Text:
1. A sorption exothermicity measurement device comprising: a dry air supplier; a humidified air supplier; at least one reaction measurer into which dry air supplied from the dry air supplier or humidified air supplied from the humidified air supplier flows to allow the supplied dry air or the supplied humidified air to come in contact with a held sample; a flow rate regulator that regulates a flow rate of at least the humidified air of the dry air or the humidified air flowing into the at least one reaction measurer; and a flow rate measurer that measures the flow rate of at least the humidified air of the dry air or the humidified air flowing into the at least one reaction measurer wherein the at least one reaction measurer comprises: a first layer that comprises a heat-insulating material, the first layer including therein a discharge hole through which inflow of the flowing dry air or humidified air occurs from one face and outflow of the dry air or the humidified air occurs toward the other face; a temperature sensor that is placed on the face, toward which the outflow of the dry air or the humidified air occurs, of the first layer; a sample holder that holds the sample sandwiched between the sample holder and the first layer such that temperature-sensing portion of the temperature sensor comes in contact with the sample in a periphery of a region containing the temperature sensor; and a second layer that comprises a heat-insulating material, the second layer being placed to face the first layer such that the sample is interposed between the first layer and the second layer in the region containing the temperature sensor.
