Liquid ejecting head and liquid ejecting apparatus

The invention provides a liquid ejecting head and a liquid ejecting apparatus. The liquid ejecting head includes: a plurality of head chips that eject liquid in a first direction; a first substrate which is a rigid substrate connected to the plurality of flexible substrates respectively provided on each of the plurality of head chips; and a second substrate which is a rigid substrate provided on the opposite side of the plurality of head chips with respect to the first substrate and on which a connector is provided, the first substrate having first and second substrate-to-substrate connectors, and the second substrate having third and fourth substrate-to-substrate connectors, the first substrate-to-substrate connector is connected to the third substrate-to-substrate connector by fitting the first substrate-to-substrate connector to the third substrate-to-substrate connector and fitting the second substrate-to-substrate connector to the fourth substrate-to-substrate connector. The second substrate-to-substrate
