A HDMI connector with anti-misinsertion structure includes a metallic case, a U-shaped plate, and a terminal base. The U-shaped plate is disposed on the upper surface of the metallic case, its front ends at which two push resilient plates and a block are disposed, respectively, its rear ends which extend to form two front arm potions connected to the push resilient plates and the block, and extends backward to form two rear arm portions and two base portions. The terminal base is installed thereon a terminal set. The anti-misinsertion structure is integrally formed with the metallic case to reduce manufacturing costs and boost linking-up and stopping strength of the anti-misinsertion structure, thereby preventing the non-HDMI plug from being inserted into the HDMI connector.
