Zusammenfassung:	An electromagnetic relay and a circuit substrate comprising the same are disclosed, for preventing erroneous operation when they are made wet by water, at low cost. The electromagnetic relay comprises a case (2) having fluid-tight characteristics; an excitation coil (3) provided in the case; and electrodes (7, 7) connected to both ends of the excitation coil in a manner such that at least a portion of each electrodes is formed outside the case and is exposed to an area where liquid can penetrate.
