A method for communication in a communication terminal having a single communication module and at least two Subscriber Identification Module cards is provided. The backing sheet includes a liquid impermeable base sheet and a layer of continuous filaments individually extending along a longitudinal direction of the absorbent article and stacked on an outer surface of the base sheet. The laser light transmittance in a used wave length range and the visible light transmittance through a portion of the structure from a surface on which the laser light is irradiated to the recording medium are in a specified range. The envelope of a plurality of input signals is sampled by sampling circuitries and the sampled envelopes are fed into a summation circuitry, in which they are summed. In another embodiment the inductor is arranged on an integrated circuit package substrate.
