A grip-type blood pressure measuring apparatus and a method of operating the apparatus are provided. The grip-type blood pressure measuring apparatus may include a pulse wave measuring sensor array comprising a plurality of pulse wave measuring sensors that are spaced apart from each other at a predetermined interval; and a blood pressure measurer configured to select a first pulse wave and a second pulse wave from among a plurality of pulse waves measured by the plurality of pulse wave measuring sensors, analyze the selected first pulse wave and second pulse wave, and determine a blood pressure based on an analysis result of the first pulse wave and the second pulse wave.
