Ultrasonic probe and manufacturing method therefor

An ultrasonic probe comprising:

• a plurality of sound absorbing bodies configured to form a sound absorbing layer;
• at least one ground connection part joined between the plurality of sound absorbing bodies;
• at least one center connection part joined between the plurality of sound absorbing bodies and including an electrode;
• a plurality of side connection parts joined between the plurality of sound absorbing bodies and disposed further outward than the at least one center connection part, the plurality of side connection parts each including an electrode;
• and
• a plurality of piezoelectric bodies disposed in front of the sound absorbing layer to be electrically connected to the at least one ground connection part, the at least one center connection part, and the plurality of side connection parts,
• wherein the at least one center connection part comprises:
• a first center connection part;
• and
• a second center connection part including a plurality of electrodes formed not to face a plurality of electrodes of the first center connection part, the second center connection part being disposed apart from the first center connection part,
• wherein the plurality of side connection parts comprise:
• a first side connection part;
• and
• a second side connection part including a plurality of electrodes corresponding to an array of a plurality of electrodes of the first side connection part,
• wherein each of the plurality of electrodes of the first side connection part is electrically connected to each of the plurality of electrodes of the second side connection part, such that the first side connection part and the second side connection part simultaneously transmit signals,
• wherein the plurality of electrodes of the first side connection part and the plurality of electrodes of the second side connection part are electrically separated from the plurality of electrodes of the first center part, or the plurality of electrodes of the first side connection part and the plurality of electrodes of the second side connection part are electrically separated from the plurality of electrodes of the second center connection part, such that the first center connection part or the second center connection part is configured to transmit signals independently of the first side connection part and the second side connection part.
