RECORDING HEAD AND RECORDING DEVICE COMPRISING SAME

摘要

[Problem] There are provided a recording head capable of reduction of variations in heat-generating temperature among heat-generating elements constituting a heat-generating-element array, and a recording device including the recording head. [Solution] A recording head according to one embodiment of the invention includes a heat radiator (40); a head base body (10) having a substrate (11) placed on or above the heat radiator (40) and a heat-generating-element array composed of a plurality of heat-generating elements (13a) arranged on or above the substrate (11); a bonding layer (17) that is interposed between the heat radiator (40) and the substrate (11) and bonds the heat radiator (40) with the substrate (11); and a plurality of spacer particles (19) arranged within the bonding layer (17) so as to abut on both of the heat radiator (40) and the substrate (11). The bonding layer (17) includes a first region (S1) situated immediately below the heat-generating-element array and a second region (S2) extending in parallel with the first region (S1). The spacer particles (19) are arranged in the second region (S2).
