A liquid ejection head including: a head body having a nozzle surface; a fixing plate including a bottom surface to be fixed to the head body and a side surface intersecting the bottom surface; and first filler filled between the head body and the side surface, wherein the side surface is in contact with a biasing plate biased from the side surface toward the head body, and the first filler is filled at least to a height of contact position between the fixed plate and the biasing plate with respect to the bottom surface.

Liquid ejection head and liquid ejection apparatus

A liquid ejecting head includes a head body, a first member that has a first surface and a second surface and that holds the head body, a second member that has a third surface and that is adhered to the first surface by a first adhesive so that the third surface is along planar directions of the second surface, and a third member that is disposed so as to extend over the second surface and the third surface and that is adhered to the second surface and the third surface by a second adhesive. At an intersection portion at which the first adhesive and the second adhesive contact, an adhesive receiving portion that accepts inflow of at least one of the first adhesive and the second adhesive is formed.

Liquid ejecting head, liquid ejecting apparatus, and production method for liquid ejecting head

Provided is a liquid ejecting head including: a first board on which a driving element for ejecting liquid is installed; a second board which is installed on the surface of the first board and covers the driving element; a wiring board that includes a first surface on which a wiring, where a driving signal is supplied to the driving element, is formed and a second surface that is at the opposite side to the first surface, and where the first surface of a first end section is joined to the surface of the first board; and a filling material which covers the wiring by being formed at least between the first surface and a wall surface of the second board, in which the height of the filling material with respect to the surface of the first board is high at the first surface side in comparison to the second surface side.
