The electromagnetic contactor includes an arc extinguishing cover having a shape in which a center portion is concaved with respect to an edge portion in a first direction and in which faces having a same height as the center portion continue in a second direction crossing the first direction; and an operation indicating piece arranged at an end of the movable contactor, to indicate a contact state of the contact by projecting from the center portion of the arc extinguishing cover or by being embedded therein. A step between the edge portion and the center portion of the arc extinguishing cover is equal to or larger than a projecting amount of the operation indicating piece that projects from the center portion of the arc extinguishing cover.
