Abstract: A sheet-like underfill material to be adhered on a circuit plane of a semiconductor wafer (6) whereupon bumps (5) are formed. The underfill material is composed of a base material (1) and an adhesive layer (2) peelably formed on the base material, and is adhered so that the bumps (5) penetrate the adhesive layer (2) and the bump top sections intrude into the base material (1). The base material (1) has a storage elastic modulus of 1.0×10 6 -4.0×10 9 Pa, a rupture stress of 1.0×10 5 -2.0×10 8 Pa, and a Yong's modulus of 1.0×10 7 -1.1×10 10 Pa, and the adhesive layer (2) has a storage elastic modulus of 1.0×10 4 -1.0×10 7 Pa, and a rupture stress of 1.0×10 3 -3.0×10 7 Pa.
