A pulse wave detection apparatus of the present invention has a sensor chip that includes a substrate (10) that has a shape of extending so as to be elongated in an X direction, and that is arranged so as to intersect an artery. A pressure sensor array (40) is formed on the substrate (10) and is made up of pressure sensor elements (41) that are arranged side-by-side in the X direction. An electrode terminal array (50B) for transmitting output from the pressure sensor elements (41) to the outside of the sensor chip is formed in a region that opposes an end portion of the pressure sensor array (40) on the substrate (10). Regions (10A, 10B) that correspond to two sides of the pressure sensor array (40) on the substrate (10) are planar surfaces on which electrode terminals are not located.
