A component supply device supplies components stored in a component storage tape to a component extracting position. The component supply device includes a component exposing unit that exposes the components in the component storage tape fed by a tape feeding unit, the component storage tape traveling on a travel path formed from a tape travel path forming unit. The component exposing unit includes a cover tape raising unit that performs a raising process for a cover tape. In the travel path formed from the tape travel path forming unit, a first path part on which the cover tape raising unit is disposed is inclined to one direction side in a Z-axis direction from an upstream side toward a downstream side in a tape feeding direction.
