A speed detector includes: a pressure sensor including a pitot tube attached to a moving body in a state in which an air inlet hole is directed toward a direction of a movement of the moving body, a diaphragm having a pressure receiving surface displaced by pressure, and a pressure-sensitive section adapted to receive force caused by the displacement to detect the pressure, the pressure sensor being disposed to the moving body and detecting the pressure caused in the pitot tube; and an operation section adapted to detect a speed of the moving body based on the difference between the pressure at rest and the pressure in movement of the moving body, wherein the pressure sensor is disposed so that a normal line of the pressure receiving surface becomes perpendicular to the direction of the movement.
