Abstract: An object to provide a hot plate making it possible to heat an object to be heated uniformly, and the hot plate of the present invention is characterized in that a resistance element having a thickness dispersion of ±3 ?m or less is formed on an insulating substrate.

Abstract: A hot plate unit capable of uniformly cooling a hot plate within a short period of time. The hot plate unit (1) includes a hot plate (3) including a heating element (10) and a casing (2) that supports the hot plate. The hot plate and the casing define an internal space S1. Two intake ports (17) and two lower opened portions (31) are formed in the bottom wall (2a) of the casing.

Abstract: An adhesive made from a thermosetting resin composition consisting of (a) a condensed polycyclic aromatic compound, (b) an aromatic crosslinking agent and (c) an acid catalyst is applied to each surface of adherends treated with a particular surface treating agent and heated at a temperature of 100.degree.-400.degree. C. in an oxidizing or non-oxidizing atmosphere to produce an adhesion structure. In order to provide a conductive adhesion structure, a conductive promotion catalyst is included in the adhesive. Further, a carbonaceous or graphitic adhesion structure is obtained by carbonization or graphitization of the adhesion structure.
