Thermal head and thermal printer provided with same

摘要

A thermal head and a printer head are disclosed. The thermal head includes heat generating members, a drive IC disposed, pads and interconnection lines which are all disposed on a substrate. The heat generating members are arranged in a first direction. The drive IC is operable to control driving of the heat generating members. The pads are operable to being electrically connected to terminals of the drive IC. The interconnection lines electrically connect each of the heat generating members to one of the pads. The pads are arranged in a first direction and constitute first pad groups and second pad groups constituted by the pads that constitute the first pad groups. The second pad groups are arranged in the first direction so as to be shifted from each other in a second direction that differs from the first direction.
