A liquid ejecting head, comprising: a flow passage through which a liquid flows; a supply flow passage which is in communication with one end of the flow passage and through which the liquid is supplied to the flow passage; an energy producing element (PZq) that produces energy for ejecting the liquid; and a nozzle which is in communication with the flow passage and from which the liquid is ejected by utilizing the energy produced by the energy producing element (PZq); wherein a direction in which a portion which is a part of the flow passage and with which the nozzle is in communication extends is defined as a first direction, a direction in which the liquid is ejected from the nozzle and which is orthogonal to the first direction is defined as a second direction (+Z), and a direction which is orthogonal to both the first direction and the second direction (+Z) is defined as a third direction, given above definition, the nozzle includes a first portion and a second portion, the second portion being located closer to the flow passage along the second direction (+Z) than the first portion is, cross-sectional area size of the first portion when viewed in the second direction (+Z) is smaller than cross-sectional area size of the second portion when viewed in the second direction (+Z), a width, in the third direction, of an overlapping portion that is a part of the second portion and is included in a first region is greater than a width, in the third direction, of a non-overlapping portion that is a part of the second portion and is included in a second region, the first region is a region where the second portion overlaps with the first portion in the second direction (+Z), and the second region is a region where the second portion does not overlap with the first portion in the second direction (+Z), characterised in that the liquid ejecting head further comprises: a discharge flow passage which is in communication with an other end of the flow passage and through which the liquid is discharged from the flow passage; wherein a ratio of the width of the non-overlapping portion in the third direction to the width of the overlapping portion in the third direction is 20% or greater and 50% or less. a flow passage through which a liquid flows; a supply flow passage which is in communication with one end of the flow passage and through which the liquid is supplied to the flow passage; an energy producing element (PZq) that produces energy for ejecting the liquid; and a nozzle which is in communication with the flow passage and from which the liquid is ejected by utilizing the energy produced by the energy producing element (PZq); wherein a direction in which a portion which is a part of the flow passage and with which the nozzle is in communication extends is defined as a first direction, a direction in which the liquid is ejected from the nozzle and which is orthogonal to the first direction is defined as a second direction (+Z), and a direction which is orthogonal to both the first direction and the second direction (+Z) is defined as a third direction, given above definition, the nozzle includes a first portion and a second portion, the second portion being located closer to the flow passage along the second direction (+Z) than the first portion is, cross-sectional area size of the first portion when viewed in the second direction (+Z) is smaller than cross-sectional area size of the second portion when viewed in the second direction (+Z), a width, in the third direction, of an overlapping portion that is a part of the second portion and is included in a first region is greater than a width, in the third direction, of a non-overlapping portion that is a part of the second portion and is included in a second region, the first region is a region where the second portion overlaps with the first portion in the second direction (+Z), and the second region is a region where the second portion does not overlap with the first portion in the second direction (+Z), characterised in that the liquid ejecting head further comprises: a discharge flow passage which is in communication with an other end of the flow passage and through which the liquid is discharged from the flow passage; wherein a ratio of the width of the non-overlapping portion in the third direction to the width of the overlapping portion in the third direction is 20% or greater and 50% or less.
