Electronic device comprising sensor module

A wearable electronic device configured to be wearable around a user's wrist, the wearable electronic device comprising:

• a housing comprising a front surface, a rear surface opposite to the front surface, and a side surface surrounding at least a part between the front surface and the rear surface and formed by a side bezel structure, wherein the side bezel structure comprises a recess structure;
• a battery disposed in the housing;
• a main printed circuit board disposed in the housing;
• and
• a sensor module at least partially disposed in the recess structure,
• wherein the sensor module comprises:
• a board;
• a biometric recognition sensor disposed on the board, wherein the biometric recognition sensor is configured to detect fingerprint information;
• a sealing member on at least a part of the board encapsulating the biometric recognition sensor together with the board;
• a biosignal sensing electrode spaced apart from the biometric recognition sensor and configured to detect a bioelectrical signal, wherein the biosignal sensing electrode is electrically connected to the board and at least partially exposed outside of the housing;
• and
• a flexible printed circuit board electrically connected to the board and configured to electrically connect the board to the main printed circuit board, and
• wherein the biosignal sensing electrode covers and contacts with the sealing member.
