Claim:
A memory element mounting method, comprising: a disposing step of disposing a memory element including an integrated circuit at a sheet of paper that is composed of a plurality of layers including a first layer serving as a base and a second layer serving as a surface with a thermoplasticity; and a surface treatment step of melting at least the surface of the sheet of paper at which the memory element is disposed in the disposing step and processing the molten surface of the sheet of paper into a predetermined surface shape, wherein the disposing step includes a holding step of holding the sheet of paper by pressing the sheet of paper, an embedding step of embedding the memory element into the first layer of the sheet of paper by inserting a memory element insertion needle into the first layer from a side of the sheet of paper held in the holding step and by making the memory element insertion needle push out the memory element, wherein the memory element insertion needle has the memory element and pushes out the memory element from a tip portion of the memory element insertion needle, and a filling step of filling, with an adhesive, a hole on the side of the sheet of paper formed due to the insertion of the memory element insertion needle in the embedding step, by inserting an adhesive injection needle into the hole and by making the adhesive injection needle push out the adhesive, wherein the adhesive injection needle has the adhesive and pushes out the adhesive from a tip portion of the adhesive injection needle.
