Abstract: A thermoelectric module includes: a lower substrate; an upper substrate that is disposed above the lower substrate and faces the lower substrate; a plurality of p-type and n-type thermoelectric elements that are disposed between the lower substrate and the upper substrate; a first electrode that is disposed on an upper surface of the lower substrate and a lower surface of the upper substrate and forms a series circuit by alternately and sequentially connecting the p-type and n-type thermoelectric elements; and a second electrode that is provided on the lower substrate and connects a thermoelectric element at an end portion of the series circuit and a post. The post includes a post main body that is formed of titanium, and a titanium passive film that covers a side surface of the post main body.

Abstract: No studies have been made regarding what kinds of refrigerants should be used in a refrigeration cycle device for a vehicle. An air conditioner (1) for a vehicle includes a refrigerant circuit (10) and a refrigerant that is sealed in the refrigerant circuit (10). The refrigerant circuit (10) includes a compressor (80), a first heat exchanger (85), which serves as a heat dissipater in a dehumidifying heating mode, an outside-air heat exchanger (82), a cooling control valve (87), and a second heat exchanger (86), which serves as an evaporator in the dehumidifying heating mode. The refrigerant is a refrigerant having a low GWP.

Abstract: A thermoelectric module for optical communication includes a first substrate and a second substrate that are a pair of substrates disposed opposite to each other, a plurality of thermoelectric conversion elements disposed between the first substrate and the second substrate, a first electrode and a second electrode that are a pair of electrodes connecting the thermoelectric conversion elements, a metallized portion disposed on the second substrate, a post electrode, of an anode, electrically connected to the first electrode and the second electrode, a post electrode, of a cathode, electrically connected to the first electrode and the second electrode, and a wire as a conductor structure electrically connecting the metallized portion and a part having a lower voltage than the post electrode of the anode.

Abstract: A method for manufacturing a thermoelectric conversion element includes forming a thermoelectric film containing a thermoelectric material on a surface of a substrate, pressing the thermoelectric film with a mold to form a pattern of the thermoelectric film on the surface of the substrate, and heating the pattern of the thermoelectric film formed on the surface of the substrate to generate the thermoelectric conversion element.

Abstract: A thermoelectric module includes a substrate; a thermoelectric element; a bonding portion including an electrode that bonds the substrate and the thermoelectric element; an organic material film that covers a front surface of the bonding portion; and an inorganic material film that covers the organic material film.

Abstract: A thermoelectric module includes a substrate, an electrode provided on a first surface of the substrate, a thermoelectric element, and a first diffusion prevention layer disposed between the electrode and the thermoelectric element. The first diffusion prevention layer includes a first material having a lower ionization tendency than that of hydrogen.
