Contact point device and electromagnetic relay

A contact point device configured to switch an electric current to flow or not by relative movement between a movable portion and a fixed portion, the contact point device comprising:

• a first contactor provided on one of the movable portion and the fixed portion as a conductive contact member having an outer side surface shaped in a column that surrounds a central axis along a relative movement direction of the movable portion and the fixed portion;
• an oscillation supporting portion that supports the first contactor at the one of the movable portion and the fixed portion to allow the central axis to oscillate;
• and
• a second contactor provided on the other of the movable portion and the fixed portion as a conductive contact member disposed opposite to the first contactor in the relative movement direction so as to be electrically connected to the first contactor by abutting against the first contactor, wherein
• one of the first contactor and the second contactor includes a plurality of first contact portions provided to surround the central axis on a plane perpendicular to the central axis,
• the other of the first contactor and the second contactor includes a second contact portion provided to protrude in the relative movement direction toward a space surrounded by the plurality of the first contact portions, and
• the second contact portion has a contact surface which is a curved surface exposed toward the space to surround the central axis.
