A pedal operation amount detection apparatus comprising: a transmitting member that transmits a pedal operation force; a movement lever disposed so as to be movable with respect to the transmitting member; a sensor rod disposed so as to be connected to the transmitting member and the movement lever; and a deformable body that is disposed on the transmitting member and is deformed when the pedal operation force or a reaction force corresponding to the pedal operation force is transmitted from the movement lever to the deformable body, the pedal operation amount detection apparatus electrically detecting a pedal operation amount based on deformation of the deformable body, the sensor rod extending through both the movement lever and the deformable body, the pedal operation amount detection apparatus further comprising: a first locking portion provided at an end portion of the sensor rod on a side where the sensor rod protrudes from the deformable body; a second locking portion provided at an intermediate portion of the sensor rod between the deformable body and the movement lever; a first elastic member that is disposed between the second locking portion and the deformable body in a natural state or a compressed state when a pedal is not operated; and a second elastic member that is disposed to so as to be connected to the movement lever and the sensor rod, and urges the movement lever to cause the movement lever to contact the second locking portion, when the pedal is operated, a load in a direction to displace the sensor rod toward the first locking portion is applied from the movement lever to the second locking portion, the sensor rod being moved toward the first locking portion in a manner such that the first elastic member is elastically deformed between the second locking portion and the deformable body, and the deformable body being deformed.
