Abstract
A production method for an organic EL element includes a step of forming an organic EL section on an organic EL section arrangement area in a first electrode section while conveying an electrode-attached substrate in a first direction, a step of forming a band-shaped conductive film along the first direction to cover the organic EL section and at least a part of an external connection area in the first electrode section while conveying the electrode-attached substrate on which the organic EL section is formed in the first direction, and a step of forming a groove section that separates the conductive film into a first part and a second part being a second electrode section by removing the conductive film in a predetermined area in a second direction while conveying the electrode-attached substrate on which the conductive film is formed in the first direction, and extends in the first direction.
