Abstract: A thermoplastic fiber sheet includes at least cellulosic fibers and thermoplastic resin fibers having a softening temperature of 100 to 140° C. A weight ratio of the cellulosic fibers to the thermoplastic resin fibers (the cellulosic fibers: the thermoplastic resin fibers) is 4:6 to 2:8, and porosity is 20 to 70%.

Abstract: The present invention provides a temperature control unit capable of efficiently controlling a temperature of a specific object with reduced risk of failure of electronic components due to leakage of a temperature control medium. The temperature control unit (1), which controls a temperature of a specific object, contains a temperature control medium, and a metal fiber sheet (50) that is formed with a space serving as a channel of the temperature control medium. The latent heat of evaporation of the temperature control medium is within the range of from 70 to 200 kJ/kg when the temperature control medium changes the state from a liquid state to a gaseous state. The volume expansion rate of the temperature control medium is at most 250 times when the temperature control medium changes the state from a liquid state to a gaseous state under atmospheric pressure.

Abstract: A resin card medium which has a substrate having electronic components mounted thereon and has sophisticated flatness and smoothness realized without providing any layer having holes for absorbing thicknesses of the electronic components; and a method for manufacturing a resin card medium.
A resin card medium laminated body before pressing is prepared by laminating, on a first plastic finishing sheet, a substrate having one electronic component or two or more electronic components installed on one side of the substrate, with the one side, on which the electronic component or electronic components are installed, facing upward, and laminating, on the substrate, mixed paper constituted of plastic fibers and plant fibers, and by subjecting the resin card medium laminated body to hot pressing at a temperature which is a softening point or more of the plastic fibers and less than a melting point of the plastic fibers.
