A stronger contact force is secured between the two. Therefore, even if it is a case where the electrical connection apparatus 1 is arrange | positioned in the LED bulb 100 over a long period of time and is arrange | positioned in the high temperature environment over a long period of time, the influence of a deformation | transformation of the 1st housing 13 is suppressed. Thus, a more stable contact state between the contact portion 24 and the conductive portion 101a can be ensured.

  Moreover, according to the electrical connection apparatus 1, the 1st contact 14 is formed of the plate-shaped member containing the part provided in rectangular shape. For this reason, when the first contact 14 is manufactured, when the material of the plurality of first contacts 14 is formed from a large plate-shaped member by punching or cutting, the plurality of first members are formed in the plate-shaped member. The material portions of the contacts 14 can be arranged in a densely packed state. Therefore, the yield in manufacturing the first contact 14 can be improved. Further, the first contact 14 extending in a rectangular shape is set so that the direction from the side connected to the second contact 18 toward the contact portion 24 is directed to the through hole 15a side through which the screw 104 passes in the base portion 15. ing. For this reason, the contact part 24 is arrange | positioned in the area | region where the fixing force of the screw | thread 104 acts firmly. Therefore, a stronger contact force can be secured between the contact portion 24 of the first contact 14 and the conductive portion 101a of the LED substrate 101.
