PURPOSE:To prevent break of a card and break and disconnection of a circuit and a conductor by storing and holding the electronic memory circuit so that most of the outside circumference face of this circuit may keep a gap for the inside face of a cavity where this circuit is stored. CONSTITUTION:Memory card main body 1 has a two-layer lamination structure consisting of upper substrate 2 and lower substrate 3. In this main body 1, cavity 7 is formed between concave 6 formed on substrate 2 and substrate 3, and electronic memory circuit 8 is stored and held in this cavity. Circuit 8 has the bottom face fixed to lower substrate 3 by adhesive, and the upper face and the side face of circuit 8 have a gap for the inside face of cavity 7. Then, main body 1 is provided with connection terminal 9, and one end of this terminal is connected to circuit 8 by conductor 10, and the other end extends to the side of main body 1. If a reinforcement material is provided in this cavity 7 or a protection material for circuit 8 is filled up in this cavity 7, it is advantageous furthermore. |
