Abstract:
1. A card key, comprising: a plate-shaped key body which is mounted with a circuit board being covered with a resin material, the circuit board being mounted with electronic parts that configure an electronic circuit for performing radio communication with an on-vehicle device; and a sheet body having an exterior appearance different from the resin material and being suitable for a card user to personalize the appearance of the card by removably fitting the sheet body to a main body recess of the key body to a main body recess of the key body; wherein the key body has a principal front surface on a side of which the electronic parts are mounted, the key body being provided with a main body recess sinking to a predetermined depth level from the principal front surface, and a key component accommodating recess further sinking to a level deeper than the main body recess and opened in a bottom surface of the main body recess; the key body forms an outline of the card key together with the sheet body fitted to the main body recess for coverage of the main body recess, wherein an inkjet accepting mat or a thermofusible transfer accepting mat that enables inkjet printing or thermofusible transfer printing is coated on the front surface of the sheet body; the sheet body and the key component accommodating recess are formed to provide a key component accommodating portion therebetween, the key component accommodating portion having a closed cross section and accommodating a key component therein, the circuit board is embedded in the resin material at a depth level that avoids the circuit board from being exposed to a bottom surface of the key component accommodating recess; and the electronic parts are embedded in the resin material at a depth level that avoids the electronic parts from being exposed to a bottom surface of the main body recess.
