There is provided a wiper arm which includes biasing means for applying a suitable biasing force to the rotation of an arm main body with respect to an arm head and enables the thickness of the wiper arm to be thinner while ensuring the suitable biasing force. A wiper arm 1 includes an arm head 2, an arm main body 3, a coil spring 4, and a spring plate 5. The arm main body 3 includes a hinge block 21 rotatably connected to the arm head 2 through a hinge pin 15 and a shaft section 22 extending from the hinge block 21. The spring plate 5 includes a front end wall 31 including an insertion hole 33 into which the shaft section 22 is inserted and leg sections 32A, 32B which are rotatably attached to the arm head 2 through a roller pin 18. The coil spring 4 is disposed to be coaxial with the shaft section 22 and is held to be sandwiched between the front end surface 21c of the hinge block 21 and the front end wall 31 of the spring plate 5.
