Abstract
An adhesive for temporarily fixing an electronic component to a solder precoat covered at least partially with an organic film, the adhesive including a principal resin, and a solvent dissolving the principal resin. The content of the solvent is 25 mass % or more and 40 mass % or less, and the organic film dissolves in the solvent when the solder precoat is melted. According thereto, the formation of an oxide film on the surface of the solder precoat can be suppressed, and poor connection between the electrode having the solder precoat and the electronic component can be suppressed.
