Abstract
L'invention concerne une tête d'impression thermique (1) comprenant un substrat (10), une couche de résistance (30), un circuit d'attaque (35), un élément d'étanchéité (43) et un premier bouchon d'écoulement de résine (50). La couche de résistance (30) comprend une pluralité d'unités de génération de chaleur (31). L'élément d'étanchéité (43) est formé par durcissement d'un matériau de résine d'étanchéité et scelle le circuit d'attaque (35). Le premier bouchon d'écoulement de résine (50) arrête l'écoulement du matériau de résine d'étanchéité. Le premier bouchon d'écoulement de résine (50) est disposé entre le circuit d'attaque (35) et la couche de résistance (30) et est en contact avec l'élément d'étanchéité (43).
