Electrical connector and method for producing same

An electric connector, which is to be arranged between a connection terminal of a first device and a connection terminal of a second device, and is configured to electrically connect the connection terminal of the first device and the connection terminal of the second device to each other,

• the electric connector comprising a composite, the composite including:
• an elastic body having a plurality of through holes that penetrate therethrough in a thickness direction;
• and
• a conductive member formed of a metal layer, which is joined to an inner wall of each of the through holes, and is configured to electrically connect the connection terminal of the first device and the connection terminal of the second device to each other,
• wherein at least a part of a vicinity of at least one of distal ends of the conductive member defines a continuous hollow in a direction parallel to the through hole,
• wherein the composite includes a protruding portion that protrudes in the thickness direction of the elastic body on at least the one principal surface side of the elastic body, wherein a first through hole of the plurality of through holes is in the protruding portion, and the first through hole has a first height;
• and
• a sheet-shaped member made of a resin, which is laminated on at least a part of a thin layer portion having a thickness smaller than a thickness of the protruding portion, on at least the one principal surface side of the elastic body, the sheet-shaped member exhibits excellent heat resistance and dimensional stability, a second through hole of the plurality of through holes is in the thin layer portion, the second through hole has a second height, and the second height is different from the first height.
