In a driving tool, a push lever plunger is moved upward by a push lever unit when the push lever unit is disposed at an uppermost position. The push lever unit includes a first protruding part and a second protruding part. The first protruding part is configured to contact a first contact part of a housing when the push lever unit is disposed at the uppermost position. The second protruding part is configured to contact a second contact part of the housing when the push lever unit is disposed at the uppermost position. A compressed air control unit, the second protruding part, and an ejection channel are disposed within an imaginary plane extending in an approximate vertical direction. The compressed air control unit is disposed on a side opposite to the second protruding part with respect to the ejection channel in a horizontal direction.
