A contact device comprising: a contact block including a plurality of fixed terminals on which fixed contacts are formed, and a movable contactor on which movable contacts contacting and leaving the fixed contacts are formed; a driving block that drives the movable contactor so that the movable contacts can contact and leave the fixed contacts; and a magnetic field forming unit that is arranged on a periphery of the contact block and forms a magnetic field, wherein the plurality of fixed terminals are formed in a columnar shape respectively and the fixed contacts are provided on ends of the fixed terminals respectively, in at least one fixed terminal among the plurality of fixed terminals, the fixed contact does not abut against the movable contact in a side opposite to other one or more fixed terminals, wherein the magnetic field forming unit includes a pair of permanent magnets arranged opposite to each other through the contact block in a direction perpendicular to a contacting/leaving direction of the movable contacts and the fixed contacts, and polarities of surfaces of the pair of permanent magnets, the surfaces being opposite to each other, are same characterized in that in the one fixed terminal, the fixed contact and the movable contact are allowed to abut against each other in an outside of the fixed contact, which is a direction other than the side opposite to the other fixed terminal, by forming (i) a step difference portion, which can be an inclined surface, on a movable contactor side, or (ii) a step difference portion, which can be an inclined surface, on a fixed terminal side. a contact block including a plurality of fixed terminals on which fixed contacts are formed, and a movable contactor on which movable contacts contacting and leaving the fixed contacts are formed; a driving block that drives the movable contactor so that the movable contacts can contact and leave the fixed contacts; and a magnetic field forming unit that is arranged on a periphery of the contact block and forms a magnetic field, wherein the plurality of fixed terminals are formed in a columnar shape respectively and the fixed contacts are provided on ends of the fixed terminals respectively, in at least one fixed terminal among the plurality of fixed terminals, the fixed contact does not abut against the movable contact in a side opposite to other one or more fixed terminals, wherein the magnetic field forming unit includes a pair of permanent magnets arranged opposite to each other through the contact block in a direction perpendicular to a contacting/leaving direction of the movable contacts and the fixed contacts, and polarities of surfaces of the pair of permanent magnets, the surfaces being opposite to each other, are same characterized in that in the one fixed terminal, the fixed contact and the movable contact are allowed to abut against each other in an outside of the fixed contact, which is a direction other than the side opposite to the other fixed terminal, by forming (i) a step difference portion, which can be an inclined surface, on a movable contactor side, or (ii) a step difference portion, which can be an inclined surface, on a fixed terminal side.
