PROBLEM TO BE SOLVED: To provide thermochromic fiber-blended paper which does not drop thermochromic fibers or thermochromic agent by abrasion, bending or the like, when the paper is made or used. SOLUTION: In the thermochromic fiber-blended paper, the fibers contains 5 to 95 mass% of thermochromic fibers kneaded with a thermochromic agent and 95 to 5 mass% of other fibers essentially consisting of pulp fibers. The thermochromic fiber-blended paper obtained by blending the thermochromic fibers kneaded with the thermochromic agent does not drop the thermochromic agent or the thermochromic fibers by abrasions or the like, and when thermally fusible fibers or hot water-soluble fibers are blended as synthetic fibers except the thermochromic fibers, a nonwoven fabric like thermochromic fiber-blended paper is obtained.
