Electronic device including coin-cell battery

A wearable electronic device comprising:

• a housing;
• a battery disposed in an inner space of the housing, the battery comprising a first surface facing a first direction, a second surface facing a second direction different from the first direction, and a third surface facing a third direction different from the first direction and the second direction, a first electrode being disposed on the first surface and a second electrode being disposed on the second surface;
• a first electrode tap extending from the first surface of the battery and being at least partially parallel to the first surface of the battery;
• a second electrode tap extending from the second surface of the battery and being at least partially parallel to the second surface of the battery;
• a printed circuit board connecting the first electrode tap to the second electrode tap on the third surface of the battery;
• and
• a peripheral member surrounding at least a portion of the third surface of the battery,
• wherein soldering parts are formed on a first surface of the printed circuit board, the first surface of the printed circuit board facing a direction parallel to the third direction, the soldering parts connecting an end of the first electrode tap to a first contact portion of the printed circuit board and an end of the second electrode tap to a second contact portion of the printed circuit board, respectively,
• wherein a solder flow control member is disposed on a second surface of the printed circuit board, the second surface of the printed circuit board facing a direction opposite to the third direction, and
• wherein a heat-resistant tape is disposed at a position corresponding to the second electrode tap on one surface of the peripheral member.
