Zusammenfassung:PROBLEM TO BE SOLVED: To provide a contact device capable of suppressing reduction of arc cut-off performance, and an electromagnetic relay mounted with the contact device.SOLUTION: A contact device 10 includes: plural fixed terminals 33 each having a fixed contact 32 form therein; a contact block 3 having a movable contact 35 formed with movable contact point 34 which comes into contact with and separates away from the fixed contact 32; and a drive block 2 that drives the movable contact 35. By disposing a permanent magnet 46 around the contact block 3, arc which occurs when the contacts come into contact with each other and separate away from each other can be eliminated. At least one fixed terminal 33 in the plural fixed terminals 33 is formed so that the fixed contact 32 and the movable contact point 34 come into contact with each other in an area other than the side opposing to the other fixed terminal 33.
