Disassemblable structure, electric equipment and non-electric equipment having disassemblable structure, and disassembling method

An electric equipment having a disassemblable structure in a portion where adherends are joined to each other,

• wherein said disassemblable structure comprises:
• a double-coated pressure-sensitive adhesive tape or a double-coated pressure sensitive adhesive sheet comprising a substrate and pressure-sensitive adhesive layers formed on both surfaces of the substrate, at least one of said pressure-sensitive adhesive layers being a thermal foaming agent-containing pressure-sensitive adhesive layer;
• a heating element which foams the thermal foaming agent-containing pressure-sensitive adhesive layer by heating;
• and
• a pair of the adherends joined to each other through the pressure-sensitive adhesive tape or sheet and the heating element,
• and wherein the electric equipment has an electric source which supplies electric power to the heating element.

• and wherein the electric equipment has a connecting terminal which supplies electric power from an external electric source to the heating element.

A non-electric equipment having a disassemblable structure in a portion where adherends are joined to each other,

• wherein said disassemblable structure comprises:
• a double-coated pressure-sensitive adhesive tape or a double-coated pressure sensitive adhesive sheet comprising a substrate and pressure-sensitive adhesive layers formed on both surfaces of the substrate, at least one of said pressure-sensitive adhesive layers being a thermal foaming agent-containing pressure-sensitive adhesive layer;
• a heating element being constituted by a metal powder which is contained in at least one of the pressure-sensitive adhesive layers formed on the both surfaces of the substrate;
• and
• a pair of the adherends joined to each other through the pressure-sensitive adhesive tape or sheet and the heating element.
