Fingerprint sensor and electronic device comprising fingerprint sensor

A fingerprint sensor comprising:

• a photo sensor;
• a first circuit board;
• and
• a second circuit board,
• wherein the first circuit board includes a first conductive pattern for recognition of an input device, and the second circuit board includes a second conductive pattern for recognition of a fingerprint, and
• wherein the second circuit board is located between at least the first circuit board and the photo sensor.

An electronic device comprising:

• a display device comprising a display;
• a battery;
• a heat radiating layer located between at least the display device and the battery;
• a fingerprint sensor including a circuit board;
• and
• a processor electrically connected to the display device and the fingerprint sensor,
• wherein the circuit board includes a conductive pattern for recognition of a fingerprint, the circuit board includes an opening through which at least a portion of a conductive metal inclusive layer included in the circuit board is exposed, and the conductive metal inclusive layer exposed through the opening is electrically connected with the heat radiating layer.
