1. An endoscope comprising:
an observation window that is provided on a distal end surface of an insertion unit bendable in an up/down direction and a left/right direction and is used to observe an inside of an object to be examined;
a first treatment tool outlet port provided on the distal end surface and configured to accommodate a first treatment tool;
a second treatment tool outlet port provided on the distal end surface and configured to accommodate a second treatment tool; and
a front water supply port that is provided on the distal end surface and jets liquid to a portion to be observed in the object to be examined,
wherein as the distal end surface is viewed from a front, a first axis and a second axis passing through a center of the distal end surface are orthogonal to each other, the first axis is parallel to the left/right direction, the second axis is parallel to the up/down direction, a center of the observation window is positioned above the first axis, a center of the first treatment tool outlet port is positioned below the first axis, and a center of the front water supply port is positioned between the center of the observation window and the center of the first treatment tool outlet port in the direction of the second axis,
wherein the center of the front water supply port is positioned between the center of the observation window and a center of the second treatment tool outlet port in the direction of the second axis,
wherein an up direction of the endoscope corresponds to an up direction of an image based on electrical signals from an image pickup element of the endoscope,
wherein in the second axis direction, the center of the second treatment tool outlet port is disposed above the center of the first treatment tool outlet port.
