Abstract
A contact point device includes a first contactor, an oscillation supporting portion, and a second contactor. The first contactor has an outer side surface shaped in a column that surrounds a central axis. The oscillation supporting portion supports the first contactor to allow the central axis to oscillate. The second contactor is disposed opposite to the first contactor. 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, and the other includes a second contact portion provided to protrude toward a space surrounded by the plurality of the first contact portions. The second contact portion has a contact surface which is a curved surface exposed toward the space to surround the central axis.
