SUBJECT of the Invention Provide the sheet|seat which a water absorption and a linear thermal expansion rate are low， and is excellent in transparency， and also excellent also in the dimensional stability under a high humidity. PROBLEM to be solved A fiber width is a sheet|seat which mix|blends microfibrous cellulose 1，000 nm or less， resin derived from one at least chosen from a water based resin emulsion and a water based resin dispersion， and a wet paper strength enhancer， Comprising: The compounding quantity of this microfibrous cellulose in solid content of this sheet|seat is 50 mass % or less， The water absorption represented by following formula (1) of this sheet|seat is 50 % or less， The linear thermal expansion rate in 100-150 degreeC is 60 ppm/K or less， And a haze is 10 % or less， Sheet|seat. Water absorption =(W-Wd)/Wd*100 (1) (Here， W is the mass after a sheet|seat is immersed in ion-exchange water for 24 hours， Wd is a sheet|seat， 23 degreeC The mass after controlling the humidity with 50% of a relative humidity for 24 hours is shown.)
