An object of the present invention is to suppress an occurrence of a vapor condensation in a contact part (30) and to prevent a failure of electric conduction due to a freeze of condensate. In an electromagnetic relay of the present invention, partition walls (13) protrude on an inner wall surface of a cover (12). A coil (21) is surrounded by the inner wall surface of the cover (12), the partition walls (13) and an upper collar part (22b) and a lower collar part (22c) of a coil bobbin (22) on which the coil is wound to isolate the coil (21) from the contact part (30) including a fixed contact (31) and a movable contact (33). Thus, air of high temperature in the periphery of the coil (21) is restrained from reaching the contact part (30). Thus, air in the periphery of the contact part (30) is held to a low temperature, so that the occurrence of the vapor condensation in the contact part(30) can be prevented. Further, when an end face of a base (11) is sliding fitted to ribs (15) formed on the cover (12), a case (1) can be simply formed. |
