Claim 5:
6. A vehicle constituent member comprising:
a body portion made of metal and having a pair of pillars, the pair of pillars including an outer pillar disposed on an outer side in a vehicle width direction and an opposite inner pillar disposed on an inner side in the vehicle width direction, the outer pillar having an outer vertical section projecting outwardly in the vehicle width direction and, the inner pillar having an inner vertical section projecting inwardly in the vehicle width direction, the inner vertical section having a first surface opposite a second surface, the first surface inward in the vehicle width direction to the second surface, the outer pillar and inner pillar having opposite ends joined as to form a hollow columnar shape;
a reinforcing member made of fiber reinforced resin and having a sheet shape, the sheet shape comprising a first end surface, a second end surface opposite the first end surface, the first end surface between the second end surface and the first surface of the inner pillar, and four peripheral edges surrounding a perimeter of the reinforcing member, one peripheral edge of the four peripheral edges is a surface end, the reinforcing member being disposed on the first surface of the inner pillar; and
an adhesive layer provided between the first surface of the inner pillar and the reinforcing member and joining the inner pillar to the reinforcing member, the adhesive layer being configured such that a thickness, in a vehicle front-rear direction, of a part of the adhesive layer becomes thinner as the part of the adhesive layer is distanced outwardly from the surface end of the reinforcing member, the part of the adhesive layer being disposed outwardly from the surface end of the reinforcing member, the thickness of the part of the adhesive layer distanced outwardly from the surface end of the reinforcing member is equal to or less than a maximum plate thickness, the maximum plate thickness being a distance between the first surface of the inner pillar and the second end surface of the reinforcing member with the adhesive layer in between, a thickness of a part of the adhesive layer distanced between the first surface of the inner pillar and the first end surface of the reinforcing member is greater than a reinforcing member thickness, the reinforcing member thickness being a distance between the first end surface and the second end surface of the reinforcing member, and
the adhesive layer includes a first portion that is disposed outwardly from the surface end of the reinforcing member, the first portion has a quadrant shape in a sectional view of the body portion along the vehicle front-rear direction,
wherein the first end surface of the reinforcing member is covered with the adhesive layer,
the reinforcing member and the adhesive layer have a first joining surface along a surface direction of the reinforcing member, a second joining surface along a thickness direction of the reinforcing member, and
all the peripheral edges of the reinforcing member are covered with the adhesive layer.
