PROBLEM TO BE SOLVED: To provide high alignment accuracy with a reduced cost, while no excessive force is being applied at inserting, for smooth inserting. SOLUTION: There are provided a first guide body 1, comprising a first guide surface 13 supported by a body, a second guide body 2 comprising a second guide surface 13 supported by the body, a third guide body 3 comprising a third guide surface 13 supported by the body, and a fourth guide body 4 comprising a fourth guide surface 13 supported by the body. The first guide surface 13 and the second guide surface 13 comprise, respectively, a first contact surface where a first end surface part of one first straight end edge region of an electronic circuit board 14 makes simultaneous contact with no force while the third guide surface 13 and the fourth guide surface 13 comprise a second contact surface, respectively, as well. The interval between a pair of guide bodies is about the width of the electronic circuit board. A sufficient space is provided between a pair of guide bodies, and a hot air passes through the space for high cooling effect. The guide surface is a conical surface tilted in two-dimensionally, providing a high guiding effect for high alignment accuracy.
