A pressure-sensitive adhesive fastener (100) is overlapped with a target object (150) on one surface (110a) side provided with a pressure-sensitive adhesive layer (121) and protruding members (130) to be coupled with the target object (150). With the pressure-sensitive adhesive fastener (100) coupled with the target object (150), the pressure-sensitive adhesive layer (121) is bonded to the target object (150), and part of column sections (131) and insertion sections (132) of the protruding members (130) enter gaps in the target object (150). This entrance creates such a mode that the protruding members (130) are stuck into the target object (150), resulting in a prevention of a shift in position between the pressure-sensitive adhesive fastener (100) and the target object (150).一種壓敏性黏著劑緊固件(100)係在具備一壓敏性黏著劑層(121)及突出構件(130)的一個表面(110a)側上與一目標物體(150)重疊以與該目標物體(150)耦合。使用與該目標物體(150)耦合之該壓敏性黏著劑緊固件(100),該壓敏性黏著劑層(121)係接合至該目標物體(150),且該等突出構件(130)之行區段(131)及插入區段(132)的部分進入該目標物體(150)中的間隙。此進入產生此一類模式,即該等突出構件(130)卡進該目標物體(150)中,導致該壓敏性黏著劑緊固件(100)與該目標物體(150)之間免於位置移位。100‧‧‧壓敏性黏著劑緊固件110‧‧‧片材基材110a‧‧‧第一表面110b‧‧‧第二表面120‧‧‧壓敏性黏著劑層121‧‧‧壓敏性黏著劑層121a‧‧‧前表面122‧‧‧壓敏性黏著劑層130‧‧‧突出構件131‧‧‧行區段132‧‧‧插入區段
