Abstract
A Peltier module comprising: thermoelectric elements in which plural p-type and n-type thermoelectric elements are alternately arranged, metal electrodes placed in both ends of the thermoelectric elements in order to connect the thermoelectric elements in series, and metal substrates on at least a part of which surfaces an insulating thin film is formed, the metal substrates being oppositely placed so as to be connected to the metal electrodes and sandwich the metal electrodes and the thermoelectric elements.

A Peltier module comprising:
- thermoelectric elements in which plural p-type and n-type thermoelectric elements are alternately arranged;
- metal electrodes placed in both ends of said thermoelectric elements in order to connect said thermoelectric elements in series;
- and
- metal substrates on at least a part of which surfaces an insulating thin film is formed, said metal substrates being oppositely placed so as to be connected to said metal electrodes and sandwich said metal electrodes and said thermoelectric elements.
A laser module comprising:
- a laser diode (LD) element;
- a photo coupling member for coupling laser light from said LD element to an optical fiber;
- and
- a temperature control member for stabilizing an oscillation state of said LD element, said temperature control member including a Peltier module comprising thermoelectric elements in which plural p-type and n-type thermoelectric elements are alternately arranged, metal electrodes placed in both ends of said thermoelectric elements in order to connect said thermoelectric elements in series, and metal substrates on at least a part of which surfaces an insulating thin film is formed, said metal substrates being oppositely placed so as to be connected to said metal electrodes and sandwich said metal electrodes and said thermoelectric elements.
A Peltier module integrated heat spreader including a Peltier module comprising thermoelectric elements in which plural p-type and n-type thermoelectric elements are alternately arranged, metal electrodes placed in both ends of the thermoelectric elements in order to connect the thermoelectric elements in series, and two metal substrates on at least a part of which surfaces an insulating thin film is formed, the metal substrates being oppositely placed so as to be connected to the metal electrodes and sandwich the metal electrodes and the thermoelectric elements, wherein one of said two metal substrates is connected to a heat generating element and a part of the remaining metal substrate is extended to form a leg portion, said leg portion covering the heat generating element mounted on an electronic board.
