PROBLEM TO BE SOLVED: To provide a disposable pocket heater having superior flexibility, abrasion resistance, heat resistance and heat-sealing property. SOLUTION: (A) This pocket heater formed by using a non-woven fabric composed of polyester fibers for a surface material is characterized in that, the surface material is composed of a resin composition containing 0.5-50 wt.% amorphous polyester component with glass transition point temperature of 50°C or more in a crystalline polyester component, a non-woven fabric formed by opening a continuous fiber whose fineness in a monofilament is 0.5-5 dtex, and then dottedly compression-bonding is used as the surface material, and portions crushed by the thermocompression-bonding are formed independent respectively, and integrally joined with one another at the formation area rate of the thermocompression-bonded part of 5-40%.
