Pad for electrodes

A pad (1) for electrodes, which is provided with: a first conductive adhesive sheet (2) that is to be connected to an arbitrary electrode; a second conductive adhesive sheet (4) that is positioned at a distance from the first conductive adhesive sheet (2) in the plane direction and is to be connected to another electrode; and a base (10) that supports the first conductive adhesive sheet (2) and the second conductive adhesive sheet (4). At least one surface of the first conductive adhesive sheet (2) and at least one surface of the second conductive adhesive sheet (4) are exposed, and the first conductive adhesive sheet (2) and the second conductive adhesive sheet (4) have a thickness compressibility of 10% or less and a thickness recovery rate of 95% or more. The base (10) is a non-conductive base having a water absorption capacity of 1-1.5 times and a water vapor permeability of 1,000 g/m 2 ·24h or more.
