FIG. 1 is a view of the housing etc. in FIG. 2 viewed from the side opposite to the wrist side, and is a view showing an example of display such as a display device. FIG. 2 is a diagram showing a circuit diagram of a pulse wave detection device to which the present invention is applied, and is a partially sectional view. FIG. 3 is a view of the housing etc. in FIG. 2 as viewed from the wrist side. FIGS. 4 and 5 are diagrams showing other display examples of the display device, etc., and correspond to FIG. 1, respectively. FIG. 6 is a flowchart for explaining the operation of the pulse wave detection device shown in FIG. 2 from when the housing is attached to the wrist to when pulse wave detection is started. FIG. 7 is a diagram illustrating a tendency of change in the amplitude of a pulse wave signal in a direction substantially perpendicular to the artery when determining the display position of the artery. 10: Housing, 12: Body surface, 36: Artery, 38: Pressure surface, 20: Pressure sensor, 42: Pressure sensitive diode (pressure detection point), 48: Outer surface, 50
