Abstract
Abstract A block-shaped IC module (1) seals an IC chip (30) by an insulator and comprises contact terminals (101 to 106; 111 to 116) and retaining means (14, 15), wherein the contact terminals (101 to 106; 111 to 116) extend from an upper surface to side surfaces of the IC module (1) and they are electrically connected to the IC chip (30) so as to send data to or receive data from the IC chip (30). A data carrier (100, 120, 140, 160) on which the IC module (1) is fitted includes a hole portion (41, 91) having holding members (42, 43; 71, 72; 92, 93) corresponding to the retaining means (14, 15) so as to be engaged with the IC module (1). Accordingly, one IC module (1) can be freely used for various data carriers. Further, the IC module (1) can be thickened as much as possible, thereby improving strength of the IC module (1).
