A physiological signal monitoring belt includes a belt-shaped unit and an electrode unit. The electrode unit is disposed on a surface of the belt-shaped unit and includes a base layer, an intermediate layer, and a conductive layer. The intermediate layer has a first surface and a second surface. The base layer is disposed on the first surface, and the conductive layer is disposed on the second surface. The electrode unit is disposed on the surface of the belt-shaped unit through the base layer.
