A fluid pressure actuator includes: an actuator body which expands and contracts through supply/discharge of a fluid to generate a driving force; a sensor for detecting a condition of the actuator body; and a control part for controlling a fluid regulator for adjusting a pressure of the fluid supplied to and discharged from the actuator body based on a detection signal from the sensor. The sensor is mounted in the actuator body.
