Abstract
An electrical connection device includes: a wiring board in which lands are arranged on a main surface; and probes. Each of the probes has a distal end portion that contacts an object to be measured and a proximal end portion that contacts the land. A material of a surface film of the proximal end portion, which contacts the land, is a metal material different in composition from a material of the land that contacts the surface film.
