摘要:
There is a need to provide a large capacity memory card for a portable communication device. A memory card 1 includes: a wiring board 2 mainly composed of a glass epoxy resin; multiple semiconductor chips (3C and 3F) mounted on a main surface of the memory card 1; and a mold resin 4 for encapsulating the wiring board 2 and the semiconductor chips (3C and 3F). The mold resin 4 is made of a thermosetting epoxy resin containing quartz filler. A back surface of the wiring board 2 is not covered with the mold resin 4 and is exposed to a back surface of the memory card 1. The back surface of the wiring board 2 is used to form multiple external connection terminals 7 electrically connected to the semiconductor chips (3C and 3F) . When the memory card 1 is attached to a card slot of a mobile phone, the external connection terminals 7 contact with a connector terminal contained in the card slot. This makes it possible to exchange signals between the memory card 1 and the mobile phone or to supply the power.
