Electronic device including reinforcement member

An electronic device comprising:

• a housing including:
• a first plate facing a first direction,
• a second plate facing a second direction opposite to the first direction, and
• a side member surrounding a space between the first plate and the second plate;
• a support member disposed in the space between the first plate and the second plate;
• a first conductive area included in the side member;
• a first circuit board disposed on one surface of the support member;
• a reinforcement member integrally formed with the support member, and protruding further than the one surface of the support member in the second direction;
• an interposer disposed adjacent to the reinforcement member;
• a second circuit board extending further than the first circuit board toward the first conductive area, and disposed on the reinforcement member;
• and
• a connection member comprising an elastic body electrically connecting the first conductive area and the second circuit board and being disposed on an edge of the second circuit board,
• wherein the first circuit board and a portion of the second circuit board do not overlap a top surface of the reinforcement member,
• wherein the connection member electrically connects the second circuit board to a protruding area included in the first conductive area, and
• wherein the protruding area protrudes from the first conductive area toward an interior of the housing.
