GAS DETECTION SHEET AND ELECTROCHEMICAL ELEMENT COMPRISING GAS DETECTION SHEET

A gas detection sheet has good gas detection sensitivity and excellent adhesion between a support and a porous coordination polymer, and an electrochemical element includes the gas detection sheet. The gas detection sheet includes a gas detection sheet support and a porous coordination polymer represented by general formula (1) supported on the support.
