PROBLEM TO BE SOLVED: To provide a friction implement configured to heat discolor only a target portion in a wide area of handwriting using a thermochromic ink on a paper face, and to prevent the contamination of a friction part of a friction body.SOLUTION: A friction body 2 is formed into a flat shape allowing a front surface 2a and a backside 2b to approximate each other, a case body 3 is formed so that a front surface wall 3a and a backside wall 3b are continuous to each other by a continuously-connecting part 3e, the friction body 2 is encased in the case 3 by being pivoted by a shaft 2f for continuously-connecting the one-end side 2c of the friction body 2 and the one-end side 3c of the case body 3, and the other end side 2d of the friction body 2 is paid out from the case body 3 by turning the friction body 2 which the shaft 2f as a fulcrum, thus forming a friction part 2h. |
