To provide a semiconductor memory card capable of improving reliability by preventing malfunction.
The semiconductor memory card 100 comprises a circuit substrate 5 provided with an input/output terminal 1 connected to an external device to input/output signals, an internal terminal 2 and substrate wiring 3 provided on the surface, and provided with a solder resist 4 which is resin for insulating and protecting the substrate wiring 3; a semiconductor memory 6 placed on the circuit substrate 5 and electrically connected to the internal terminal 2 to store requested data; and an insulating seal 7 provided on the circuit substrate 5 to cover at least the internal terminal 2 and to insulate the internal terminal 2 from the outside. The outer peripheral part of the insulating seal 7 is bonded into a position lower than the surface height of the solder resist 4.
