。In order to solve the above-mentioned drawbacks, a heat-retaining mat made of carbon black formed into a sheet has been proposed. However, although mats containing carbon black have excellent heat retention properties, when used for example in X-ray photography, they have low X-ray transmittance, so it is necessary to increase the X-ray emissivity. The disadvantage is that the exposure rate increases.

In order to obtain a planar heat-generating sheet having a particularly stable heat-generating effect, pitch-based carbon fibers are preferably used.In order to obtain a planar heat-generating sheet having a particularly stable heat-generating effect, at least two different lengths of 3 m or more and less than 5 m and 5 nn or more and 1 ol 11 or less are used. It is desirable to use carbon fibers having a thickness of Synthetic pulp can also be added. Preferred examples of the plant valves include wood fibers, seed hair fibers, bast fibers, single-leaf fibers, and fibers of the plant family, and raw material monomers for obtaining synthetic pulp include acrylonitrile, vinyl acetate, and vinylidene chloride. ,

The blending ratio of the carbon fiber and pulp is preferably 3 to 50% by weight of carbon fiber, preferably 8 to 20% by weight, and 97 to 50% by weight of pulp. In this case, if the carbon fiber is less than 3% by weight, If the electrical resistance becomes high and the desired exothermic temperature cannot be obtained, and if it exceeds 50%, the dispersion rate becomes poor and stable electrical resistance cannot be obtained, and there is a risk that the X-ray transmittance will decrease. I don't like it because it is.

and 75 g of kraft pulp (N-B KP) were put into a small test mixer together with water, and mixed and stirred for 10 seconds to disperse each component. Next, 8 g of 4-length PAN-based carbon fiber was added and mixed and stirred again for 10 seconds. The obtained dispersion was poured into a 250 x 250n* tap machine to form a sheet with a basis weight of 40 g/rrr, and then passed through a drying drum to obtain a test piece of a carbon fiber-mixed heat generating sheet with a thickness of O and 1 m. . A heat generating sheet obtained in the same manner as the test piece was cut to 1700 x 550 m, silver paste was pasted along two opposing sides of the heat generating sheet, and then copper foil auxiliary electrodes were attached along the silver paste. A planar heat generating sheet was prepared. Next, the obtained planar heat generating sheet was used as a urethane resin mat (trade name: PEF).

When a current of 0 V was applied, the surface temperature of the mat rose to 35° C. in 3 minutes, and after that the surface temperature of the mat remained almost constant. First, the xi transmittance of the planar heating sheet was measured. For this purpose, a similar carbon fiber mixed sheet is provided.

When a current was passed through the heat generating sheet made of the obtained carbon black in the same manner as in Example 1, stable heat generation was obtained. In addition, the transmittance of X-rays was measured in the same manner as in Example 1. The results are shown in Table 1.
