An electromagnetic relay including an electromagnet block having a rod-shaped iron core, a coil wound around the rod-shaped iron core, and a spool interposed between the coil and iron core. A yoke having one end section extends to a section at a side of a magnet pole section of the iron core. An end section of the yoke is arranged so that the magnet pole section has a gap on a base side. A moving iron is pivotably supported by an elastic support of a hinge spring. The electromagnet block is magnetized wherein a section drawn in the moving iron is drawn to the magnet pole section and pivoted to drive a contact switching unit. The hinge spring includes an elastic contacting portion extending toward an opposite side to the elastic support. The moving iron is integrated with a card member that comes in contact with the elastic contacting portion.

Provided is a technology which has a simple structure, is easy to manufacture, and does not increase cost. A terminal member to be press-fitted into a terminal hole formed in a base, includes a press-fitted portion which is to be press-fitted in the terminal hole, and a terminal portion extending from the press-fitted portion and protruding from the base. The terminal portion is formed by folding a plate-like body such that folded portions overlap a planar portion. At least one of the folded portions has a cut-away portion extending from the base, respectively at an edge near the press-fitted portion. A sealing agent can be injected into the terminal hole via the cut-away portions.

An electromagnetic relay including a contact switching unit having a pair of contacts. An electromagnet block drives the contact switching unit to open and close the contacts. An arc-extinguishing member includes a connection member and permanent magnets. The connection member is formed by connecting, via a middle part, opposing walls arranged in a direction perpendicular to the touch/separation direction of the contacts. Permanent magnets are disposed on opposing sections of the opposing walls.
