A driving apparatus comprises: an electro-mechanical conversion element; a driving member that reciprocates in response to an extension and contraction of the electro-mechanical conversion element; and a driven member, frictionally engaged with the driving member, that moves by reciprocating the driving member, wherein the driving member comprises a shaft portion which extends in a direction of extension and contraction of the electro-mechanical conversion element in a position which lies on a side of the electro-mechanical conversion element, and the driven member is frictionally engaged with the shaft portion.
