Electronic device including housing having dissimilar metals

An electronic device comprising:

• a side bezel structure comprising:
• a first body surrounding at least a portion of an inner space of the electronic device,
• a second body extending from the first body into the inner space and the second body comprising a through hole,
• a conductive portion comprising a first metal having a first hardness, and
• a non-conductive portion in contact with the conductive portion;
• a plate comprising:
• a support portion within the inner space, and
• a protrusion portion extending from the support portion into the through hole, the protrusion portion being coupling to the second body and being corresponding to a shape of the through hole, and
• a second metal having a second hardness lower than the first hardness;
• a conductive adhesive member electrically connecting the through hole and the protrusion portion, conductive adhesive member being disposed between the through hole and the protrusion portion;
• and
• a wireless communication circuit operatively coupling with the conductive portion,
• wherein a cross-sectional area of the protrusion portion is narrower than a cross-sectional area of the protrusion portion contacting another surface of the second body,
• wherein the cross-sectional area of the protrusion portion contacts one surface of the second body toward the support portion, and
• wherein the another surface of the second body is opposite to the one surface of the second body.
