Claim:
1. A contact pin to electrically connect a first electrical component and a second electrical component, the contact pin comprising: a lower contact portion to be electrically connected to a contact point of the first electrical component; a spring portion that is provided so as to extend above the lower contact portion, and in a pressed state, elastically deforms; a linear portion provided so as to extend upward from an upper end of the spring portion; and an upper contact portion that is formed on an upper end side of the linear portion, and in the pressed state, is brought into pressure contact with a terminal of the second electrical component by an elastic force of the spring portion, wherein the upper contact portion includes, a single first contact protrusion arranged on an extension of the linear portion such that, in the pressed state, a contact pressure of a distal end portion of the first contact protrusion with the terminal of the second electrical component is at a first level, and a plurality of second contact protrusions arranged at respective positions off the extension of the linear portion such that, in the pressed state, a contact pressure of a distal end portion of each of the plurality of second contact protrusions with the terminal of the second electrical component is at a second level lower than the first level.
