RFID tag and method for producing the same

An RFID tag comprising:

• an RFIC element that is a chip-shaped component that is configured to process the transmission and reception of a data communication signal;
• and
• an inductor element including a substrate having a mounting surface coupled to the RFIC element and a coiled antenna disposed in the substrate, such that at least a portion of an opening of the coiled antenna does not overlap the RFIC element when viewed in a direction of the winding axis of the coiled antenna,
• wherein a mounting surface of the chip-shaped component that faces the mounting surface of the substrate has an area that is larger than an opening area of the coiled antenna viewed in the direction of the winding axis.

A method for manufacturing an RFID tag comprising:

• preparing a wafer configured as a material of an RFIC element that includes at least one chip-shaped component configured to process the transmission and reception of a data communication signal and that is;
• preparing multiple inductor elements each having a coiled antenna formed in a substrate;
• electrically connecting the multiple inductor elements onto the wafer such that a winding axis of each coiled antenna is parallel to or inclined with respect to a mounting surface of the substrate;
• and
• dicing the wafer into a plurality of pieces to form individual RFID tags that each include one of the multiple inductor elements and the at least one chip-shaped component mounted thereto,
• wherein an area of a mounting surface of the at least one chip-shaped component that faces the mounting surface of the substrate of the respective individual RFID tag is larger than an opening area of the coiled antenna viewed in a direction of the winding axis of the coiled antenna.
