Abstract: A mounting structure includes a bonding material (106) that bonds second electrodes (104) of a circuit board (105) and bumps (103) of a semiconductor package (101), the bonding material (106) being surrounded by a first reinforcing resin (107). Moreover, a portion between the outer periphery of the semiconductor package (101) and the circuit board (105) is covered with a second reinforcing resin (108). Even if the bonding material (106) is a solder material having a lower melting point than a conventional bonding material, high drop resistance is obtained.
