An electric heater (10, 30, 40, 50, 60, 70, 100), such as for heating surfaces of components, onto which the electric heater (10, 30, 40, 50, 60, 70, 100) is pushed or placed, has at least one tubular heating element (1, 11, 31, 41, 51, 61, 71, 82, 101), which has a metal jacket, and with at least one contact area. The tubular heating element (1, 11, 31, 41, 51, 61, 71, 82, 101) is at least partly embedded in at least one powder or granular material (2, 32, 42, 52, 62, 72, 102). The powder or granular material (2, 32, 42, 52, 62, 72, 102) abuts against at least parts of the at least one contact area. A process is also provided for manufacturing the electric heater having at least the steps of providing at least one contact area and at least one tubular heating element (1, 11, 31, 41, 51, 61, 71, 82, 101) arranged in relation to the contact area, at least partial embedding the tubular heating element in the powder or granular material (2, 32, 42, 52, 62, 72, 102), which abuts at least partly against the at least one contact area, and compressing at least the powder or granular material (2, 32, 42, 52, 62, 72, 102). |
