Imaging lens module and mobile terminal

An imaging lens module, comprising:

• an imaging lens assembly comprising at least one lens element;
• a first optical component, which is a barrel;
• and
• at least one second optical component having a non-circular opening hole;
• wherein the lens element comprises at least one effective optical portion, which is disposed on a center of the lens element;
• wherein the first optical component comprises a side wall being closed-shape and an end wall, and the end wall is connected to one end of the side wall and has a circular opening hole;
• wherein the second optical component and the imaging lens assembly are disposed in the first optical component, and the non-circular opening hole of the second optical component is corresponded to the circular opening hole of the first optical component;
• wherein a line distance between any two points of a peripheral edge of the non-circular opening hole of the second optical component through a center of the non-circular opening hole of the second optical component is m2AA′, a minimum line distance between two points of the peripheral edge of the non-circular opening hole of the second optical component through the center of the non-circular opening hole of the second optical component is m2BB′, a maximum line distance between two points of the peripheral edge of the non-circular opening hole of the second optical component through the center of the non-circular opening hole of the second optical component is m2CC′, an angle between the line distance m2AA′ and the minimum line distance m2BB′ is κ2AB, and the following conditions are satisfied:
• m2BB′≤m2AA′<m2CC′, and
• 54 degrees≤|κ2AB|≤90 degrees,
• wherein |κ2AB| is smaller than or equal to 90 degrees.
