The invention provides a joining film having sufficient connection heat resistance and high reliability, for which a joining process of joining a semiconductor element and a substrate is simple and easy, a tape for wafer processing, a method for producing a joined body, and a joined body. Disclosed is a joining film for joining a semiconductor element and a substrate, the joining film having an electroconductive joining layer formed by molding an electroconductive paste containing metal fine particles (P) into a film form; and a tack layer having tackiness and being laminated with the electroconductive joining layer. The tack layer is thermally decomposed by heating at the time of joining, the metal fine particles (P) of the electroconductive joining layer are sintered, and thereby the semiconductor element and the substrate are joined. |
