[Problem] There are provided a thermal recording head capable of making proper operation of a converter, and a thermal recording apparatus including the same. [Solution] A thermal recording head () of the invention is driven on a basis of a first control signal and includes a head substrate () including heat generating elements (), a wiring substrate () including, on its surface, a wiring pattern () for transmission of the first control signal, and a mount substrate () disposed facing a back surface of the head substrate () and a back surface of the wiring substrate () and configured to mount the head substrate () and the wiring substrate (). On the surface of the head substrate () is placed a control element () electrically connected to the heat generating elements () and configured to control driving of the heat generating elements (). On the surface of the wiring substrate () is placed a converter () electrically connected to the wiring pattern () and configured to convert the first control signal into a second control signal. The mount substrate () is spaced away from a corresponding region at the back surface of the wiring substrate () that corresponds to a fourth placement area () bearing the converter () on the surface of the wiring substrate ().

Thermal recording head and thermal recording apparatus comprising the same

The present invention provides a recording head for a photographic printing device. The recording head of the present invention includes on a substrate two heating elements arranged adjacently and parallel to each other on a substrate. Each of the heating elements has connected to its ends a connection section, the connection sections and the heating element lying in a straight line. First and second connection sections are connected to the first heating element and third and fourth connection sections are connected to the second heating element. The heat capacities of the first and fourth connection sections are different from that of the second and of the third connection sections. The heat capacities of the first and fourth connection sections are substantially the same, as are the heat capacities of the second and third connection sections.
