<p>A warmer to be used in contact with a face easily deforms following the unevenness of the face. A warmer (1) has heating sections (11-14) where a heat generating body (31) is interposed between a first surface sheet (4) and a second surface sheet (5), and deformation sections (16-18) are formed between the heating sections. The deformation sections (16-18) are formed without the heat producing body (31) so as to be easily bendable.</p>
