Contact-type testing device and environmental test method

A contact-type testing device comprising:

• a heating plate capable of being heated and in which a desired test can be conducted while a test object is in contact with the heating plate;
• and
• a heating member that heats the heating plate,
• wherein the heating member includes:
• a plurality of strips of heat generation bodies;
• and
• a power feeding section that feeds electricity to the heat generation bodies,
• wherein the heat generation bodies are distributed in a planar manner, said plurality of the heat generation bodies are electrically parallel-connected with the power feeding section,
• wherein the parallel-connected heat generation bodies have a steep temperature and resistance characteristic that represents a relationship of the resistance value to the temperature, and resistance values of the heat generation bodies increase with temperature,
• wherein the heating member is disposed to face the heating plate, and a space is provided between the heating plate and the heating member to thereby cause distribution of heat from the heating member to the heating plate,
• whereby with a test object in contact with the heating plate to overlap multiple, selected heat generating bodies that are electrically parallel-connected, an amount of heat generated by the heat generation bodies changes in response to a temperature of an overlapping test object.
