At the stage of fastening the first connecting member 130 and the third connecting member 150, the second connecting member 140 is already fastened to the terminal block main body 21.

The fastening work for fastening the first connecting member 130 and the third connecting member 150 is performed through the openings 23 and 24 of the housing 22. More specifically, the fastening work is performed by inserting the tools used for fastening the fastening members B1 and B3 and the fastening members B1 and B3 into the inside of the housing 22 through the openings 23 and 24. At this time, the metal powder generated in the fastening work may move toward the second connecting member 140 as a foreign substance. Even when the metal powder moves toward the second connecting member 140, the upright portion 65 and the upright resin portion 102 can prevent the metal powder from reaching the second connecting member 140.

The effect of this embodiment will be described.
(1) The negative electrode bus bar 60 includes a first negative electrode fastening portion 61, a second negative electrode fastening portion 84, a third negative electrode fastening portion 90, and an upright portion 65. The upright portion 65 is provided between the first negative electrode fastening portion 61 and the second negative electrode fastening portion 84, and between the second negative electrode fastening portion 84 and the third negative electrode fastening portion 90. The resin portion 100 includes an upright resin portion 102 provided on the upright portion 65. The upright portion 65 and the upright resin portion 102 prevent the metal powder from reaching the second negative electrode fastening portion 84. Since the metal powder does not easily adhere to the second connecting member 140, it is possible to prevent the metal powder from adhering to the second connecting member 140 to cause a short circuit in the second connecting member 140.

(2) The upright portion 65 is a part of the negative electrode bus bar 60. A part of the negative electrode bus bar 60 can also be used as a member for suppressing the metal powder from reaching the second negative electrode fastening portion 84.

(3) The strength of the upright resin portion 102 can be reinforced by providing the upright portion 65. The strength of the upright resin portion 102 can be improved as compared with the case where only the upright resin portion 102 is used as a member for suppressing the metal powder from reaching the second negative electrode fastening portion 84.

(4) The upright resin portion 102 is provided so as to cover the upright portion 65. It is possible to prevent the fastening members B1, B2, B3, B4 and the tool from coming into contact with the upright portion 65 when the fastening operation is performed. It is possible to suppress the generation of metal powder from the upright portion 65.

(5) The upright portion 65 includes a fourth negative electrode fastening portion 94. Since the upright portion 65 includes the fourth negative electrode fastening portion 94, the thickness direction of the first negative electrode fastening portion 61 and the thickness direction of the fourth negative electrode fastening portion 94 are different. In other words, the directions for fastening the fastening members B1 and B4 are different between the first negative electrode fastening portion 61 and the fourth negative electrode fastening portion 94. Due to the shape of the fourth positive electrode connecting member 161 and the fourth negative electrode connecting member 162, and the restrictions on the arrangement of the terminal block main body 21 and the fourth connecting member 160, the fastening member B4 is orthogonal to the thickness direction of the first negative electrode fastening portion 61. It may be necessary to fasten from. Even in such a case, the upright portion 65 is provided with the fourth negative electrode fastening portion 94, so that the fourth connection member 160 and the terminal block 20 can be connected to each other.

(6) The housing 22 includes openings 23 and 24. Since the fastening work is performed through the openings 23 and 24, it is difficult to visually recognize that metal powder is generated. Then, it is difficult to recognize that the metal powder is generated, and the metal powder may not be removed from the housing 22. Even in such a case, it is possible to prevent the metal powder from reaching the second connecting member 140.

The embodiment can be modified and implemented as follows. The embodiments and the following modifications can be implemented in combination with each other within a technically consistent range.
○ The terminal block 20 may be provided with the terminal block main body 21 and may not be provided with the housing 22.

○ The upright portion 65 may not include the fourth negative electrode connecting portion 93 and the fourth negative electrode fastening portion 94.
○ The upright portion 65 may be provided at least between the first negative electrode fastening portion 61 and the second negative electrode fastening portion 84.

○ The entire main body portion 66 may be covered with the upright resin portion 102.
○ The negative electrode bus bar 60 may include at least a first negative electrode fastening portion 61, a first negative electrode connecting portion 64, an upright portion 65, a second negative electrode connecting portion 80, and a second negative electrode fastening portion 84.

○ The positive electrode bus bar 30 may be provided with an upright portion. In this case, an upright portion is provided between the first positive electrode fastening portion 31, the third positive electrode fastening portion 41, and the second positive electrode fastening portion 35.
○ As shown in FIG. 5, the upright portion 65 may be provided in at least a part of the upright resin portion 201. In the example shown in FIG. 5, the upright resin portion 201 has a rectangular plate shape. The upright portion 65 includes a first wall portion 202 and a second wall portion 203. The first wall portion 202 and the second wall portion 203 are provided at both ends of the upright resin portion 201 in the long side direction. An upright portion 65 is not provided between the first wall portion 202 and the second wall portion 203. It can be said that the upright portion 65 is not provided between the first wall portion 202 and the second wall portion 203 of the upright resin portion 201.
