Definitions
- the heat generating substrate 1 is arranged on the first support surface 81 of the heat dissipation member 8 . Then, by applying heat, the adhesive member 85 is solidified. This heating causes the first substrate 5, which has a higher coefficient of linear expansion than the heat generating substrate 1, to expand, thereby correcting the curvature of the heat generating substrate 1. At this time, the second regions 12b located at both ends in the x direction of the back surface 12 of the heat generating substrate are relatively loosely adhered to the first support surface 81 by the adhesive member 86. Therefore, in the heat generating substrate 1, internal stress at the curved portion is more likely to be released than when the second region 12b is bonded by the adhesive member 85.
- the fourth region 52b is bonded to the heat dissipation member 8 via the adhesive member 86, which has a weaker adhesive force than the adhesive member 85. Therefore, in the manufacturing process, it is possible to suppress the placement position of the first substrate 5 from shifting until the adhesive member 85 is solidified.
- a heat generating substrate (1) having a heat generating substrate main surface (11) and a heat generating substrate back surface (12) facing oppositely to each other in the thickness direction (z direction); a plurality of heat generating parts (41) arranged on the main surface side of the heat generating substrate and arranged along the main scanning direction (x direction); a heat dissipating member (8) on which the heat generating board is mounted; Equipped with The back side of the heat generating board is a first region (12a) located at the center in the main scanning direction and bonded to the heat dissipation member via an adhesive member (85); a second region (12b) located at both ends in the main scanning direction and not overlapping the adhesive member when viewed in the thickness direction;
- a thermal print head (A1) having: Appendix 2.

Abstract
La présente invention concerne une tête d'impression thermique comprenant un substrat de génération de chaleur, une pluralité de parties de génération de chaleur, et un élément de dissipation de chaleur. Le substrat de génération de chaleur a une surface principale de substrat de génération de chaleur et une surface arrière de substrat de génération de chaleur qui sont en regard des côtés opposés dans la direction de l'épaisseur. La pluralité de parties de génération de chaleur sont disposées sur le côté de surface principale de substrat de génération de chaleur selon une direction de balayage principale. Le substrat de génération de chaleur est monté sur l'élément de dissipation de chaleur. La surface arrière de substrat de génération de chaleur a une première zone et des secondes zones. La première zone est au centre dans la direction de balayage principale et est collée à l'élément de dissipation de chaleur par un élément adhésif. Les secondes zones sont à des extrémités respectives dans la direction de balayage principale et ne chevauchent pas l'élément adhésif tel que vu dans la direction de l'épaisseur.
