    • Thickness of an IC card is decreased, and the manufacturing efficiency of the IC card is enhanced so as to reduce the manufacturing cost. The IC card comprises: a semiconductor element 14 having electrodes; a plane coil 12 formed in such a manner that a conductor 12b is wound on the same face, having terminals 12a at respective ends; bonding wires 16 for electrically connecting terminals at both ends of the plane coil to the electrodes of the semiconductor element; and resin films 10 for sealing the semiconductor element, plane coil and bonding wires 16 when they are interposed between the resin films, wherein the thickness of the semiconductor element 14 is smaller than the thickness of the plane coil 12 and does not interfere with the conductor of the plane coil, and a thin wall thickness portion 12c is formed on a front face of the conductor of the plane coil through which the bonding wires can pass without protruding from the region of the thickness of the plane coil.
    • 降低IC卡的厚度,提高IC卡的制造效率,降低制造成本。 IC卡包括:具有电极的半导体元件14; 以使导体12b缠绕在同一面上的方式形成的平面线圈12,在端部具有端子12a; 用于将平面线圈两端的端子电连接到半导体元件的电极的接合线16; 以及树脂膜10,用于当半导体元件14的厚度小于平面线圈12的厚度并且不干扰导体时,将半导体元件,平面线圈和接合线16密封在树脂膜之间 并且在平面线圈的导体的正面上形成薄壁厚部12c,接合线可以通过该前导面而不从平面线圈的厚度区域突出。
