Summary:PURPOSE:To easily distinguish energizing/disenergizing by arranging a top cloth thin with light colour, white or transparent, providing a reversible-heat sensitive-discolouring sheet which is composed by milling a reversible-heat sensitive-discolouring material formed in a capsule into resin compound between a heater unit and the top cloth and integrally composing them. CONSTITUTION:A reversible-heat sensitive-discolouring sheet 3 is located inside a top cloth 1. The top cloth 1 is composed of woven fabric or nit of light colour, white or transparent nylon or polyester and is thin and also is joined with the reversible-heat sensitive-discolouring sheet 3 at its rear face. On the surface of the top cloth 1, colouring of the reversible-heat sensitive-discolouring sheet 3 at present which is mixed with the colour of the top cloth 1 appears. Thus, energizing/disenergizing is easily distinguished by colour change of the reversible-heat sensitive-discolouring sheet 3.
